Some attention has been paid to make this software easily
configurable and extendable. For instance, all monitor commands are
implemented with the same call interface, so that it's very easy to
add new commands. Also, instead of permanently adding rarely used
code (for instance hardware test utilities) to the monitor, you can
load and run it dynamically.

Prepare for release of version 0.2.0
2002-12-17 17:55:09 +00:00
Versioning:
===========
U-Boot uses a 3 level version number containing a version, a
sub-version, and a patchlevel: "U-Boot-2.34.5" means version "2",
sub-version "34", and patchlevel "4".
The patchlevel is used to indicate certain stages of development
between released versions, i. e. officially released versions of
U-Boot will always have a patchlevel of "0".

Software Configuration:
=======================
Configuration is usually done using C preprocessor defines; the
rationale behind that is to avoid dead code whenever possible.
There are two classes of configuration variables:
* Configuration _OPTIONS_:
These are selectable by the user and have names beginning with
"CONFIG_".
* Configuration _SETTINGS_:
These depend on the hardware etc. and should not be meddled with if
you don't know what you're doing; they have names beginning with
"CFG_".
Later we will add a configuration tool - probably similar to or even
identical to what's used for the Linux kernel. Right now, we have to
do the configuration by hand, which means creating some symbolic
links and editing some configuration files. We use the TQM8xxL boards
as an example here.
Selection of Processor Architecture and Board Type:
---------------------------------------------------
For all supported boards there are ready-to-use default
configurations available; just type "make <board_name>_config".
Example: For a TQM823L module type:
cd u-boot
make TQM823L_config
For the Cogent platform, you need to specify the cpu type as well;
e.g. "make cogent_mpc8xx_config". And also configure the cogent
directory according to the instructions in cogent/README.
Configuration Options:
----------------------
Configuration depends on the combination of board and CPU type; all
such information is kept in a configuration file
"include/configs/<board_name>.h".
Example: For a TQM823L module, all configuration settings are in
"include/configs/TQM823L.h".
* Vince Husovsky, 7 Nov 2002: Add "-n" to linker options to get rid of "Not enough room for program headers" problem * Patch by David Mller, 05 Nov 2002 Rename CONFIG_PLL_INPUT_FREQ to CONFIG_SYS_CLK_FREQ so we can use an already existing name * Patch by Pierre Aubert, 05 Nov 2002 Hardware related improvements in FDC boot code * Patch by Holger Schurig, 5 Nov 2002: Make the PXA really change it's frequency * Patch by Pierre Aubert, 05 Nov 2002 Add support for slave serial Spartan 2 FPGAs * Fix uninitialized memory (MAC address) in 8xx SCC/FEC ethernet drivers
2002-11-10 22:06:23 +00:00
Many of the options are named exactly as the corresponding Linux
kernel configuration options. The intention is to make it easier to
build a config tool - later.

Initial revision
2002-11-03 00:24:07 +00:00
CONFIG_CLOCKS_IN_MHZ
U-Boot stores all clock information in Hz
internally. For binary compatibility with older Linux
kernels (which expect the clocks passed in the
bd_info data to be in MHz) the environment variable
"clocks_in_mhz" can be defined so that U-Boot
converts clock data to MHZ before passing it to the
Linux kernel.
When CONFIG_CLOCKS_IN_MHZ is defined, a definition of
"clocks_in_mhz=1" is automatically included in the
default environment.

2003-10-09 20:09:04 +00:00
CONFIG_MEMSIZE_IN_BYTES [relevant for MIPS only]
When transfering memsize parameter to linux, some versions
expect it to be in bytes, others in MB.

- Pre-Boot Commands:
CONFIG_PREBOOT
When this option is #defined, the existence of the
environment variable "preboot" will be checked
immediately before starting the CONFIG_BOOTDELAY
countdown and/or running the auto-boot command resp.
entering interactive mode.
This feature is especially useful when "preboot" is
automatically generated or modified. For an example
see the LWMON board specific code: here "preboot" is
modified when the user holds down a certain
combination of keys on the (special) keyboard when
booting the systems
- Serial Download Echo Mode:
CONFIG_LOADS_ECHO
If defined to 1, all characters received during a
serial download (using the "loads" command) are
echoed back. This might be needed by some terminal
emulations (like "cu"), but may as well just take
time on others. This setting #define's the initial
value of the "loads_echo" environment variable.

CONFIG_ETHADDR
CONFIG_ETH2ADDR
CONFIG_ETH3ADDR
Define a default value for ethernet address to use
for the respective ethernet interface, in case this

- IP address:
CONFIG_IPADDR
Define a default value for the IP address to use for
the default ethernet interface, in case this is not

systems send out BOOTP requests at precisely the same
moment (which would happen for instance at recovery
from a power failure, when all systems will try to
boot, thus flooding the BOOTP server. Defining
CONFIG_BOOTP_RANDOM_DELAY causes a random delay to be
inserted before sending out BOOTP requests. The
following delays are insterted then:
1st BOOTP request: delay 0 ... 1 sec
2nd BOOTP request: delay 0 ... 2 sec
3rd BOOTP request: delay 0 ... 4 sec
4th and following
BOOTP requests: delay 0 ... 8 sec

If CONFIG_BOOTP_DNS2 is enabled, the secondary DNS
serverip will be stored in the additional environment
variable "dnsip2". The first DNS serverip is always
stored in the variable "dnsip", when CONFIG_BOOTP_DNS
is added to the CONFIG_BOOTP_MASK.
CONFIG_BOOTP_SEND_HOSTNAME - Some DHCP servers are capable
to do a dynamic update of a DNS server. To do this, they
need the hostname of the DHCP requester.
If CONFIG_BOOP_SEND_HOSTNAME is added to the
CONFIG_BOOTP_MASK, the content of the "hostname"
environment variable is passed as option 12 to
the DHCP server.

- Status LED: CONFIG_STATUS_LED
Several configurations allow to display the current
status using a LED. For instance, the LED will blink
fast while running U-Boot code, stop blinking as
soon as a reply to a BOOTP request was received, and
start blinking slow once the Linux kernel is running
(supported by a status LED driver in the Linux
kernel). Defining CONFIG_STATUS_LED enables this
feature in U-Boot.
- CAN Support: CONFIG_CAN_DRIVER
Defining CONFIG_CAN_DRIVER enables CAN driver support
on those systems that support this (optional)
feature, like the TQM8xxL modules.

When a board is reset during an i2c bus transfer
chips might think that the current transfer is still
in progress. On some boards it is possible to access
the i2c SCLK line directly, either by using the
processor pin as a GPIO or by having a second pin
connected to the bus. If this option is defined a
custom i2c_init_board() routine in boards/xxx/board.c
is run early in the boot sequence.

Enables a software (bit-bang) SPI driver rather than
using hardware support. This is a general purpose
driver that only requires three general I/O port pins
(two outputs, one input) to function. If this is
defined, the board configuration must define several
SPI configuration items (port pins to use, etc). For
an example, see include/configs/sacsng.h.

these parameters.
Alternatively, if you #define _both_ CONFIG_ETHADDR
_and_ CONFIG_OVERWRITE_ETHADDR_ONCE, a default
ethernet address is installed in the environment,
which can be changed exactly ONCE by the user. [The
serial# is unaffected by this, i. e. it remains
read-only.]
- Protected RAM:
CONFIG_PRAM
Define this variable to enable the reservation of
"protected RAM", i. e. RAM which is not overwritten
by U-Boot. Define CONFIG_PRAM to hold the number of
kB you want to reserve for pRAM. You can overwrite
this default value by defining an environment
variable "pram" to the number of kB you want to
reserve. Note that the board info structure will
still show the full amount of RAM. If pRAM is
reserved, a new environment variable "mem" will
automatically be defined to hold the amount of
remaining RAM in a form that can be passed as boot
argument to Linux, for instance like that:
setenv bootargs ... mem=\$(mem)
saveenv
This way you can tell Linux not to use this memory,
either, which results in a memory region that will
not be affected by reboots.
*WARNING* If your board configuration uses automatic
detection of the RAM size, you must make sure that
this memory test is non-destructive. So far, the
following board configurations are known to be
"pRAM-clean":
ETX094, IVMS8, IVML24, SPD8xx, TQM8xxL,
HERMES, IP860, RPXlite, LWMON, LANTEC,
PCU_E, FLAGADM, TQM8260
- Error Recovery:
CONFIG_PANIC_HANG
Define this variable to stop the system in case of a
fatal error, so that you have to reset it manually.
This is probably NOT a good idea for an embedded
system where you want to system to reboot
automatically as fast as possible, but it may be
useful during development since you can try to debug
the conditions that lead to the situation.
CONFIG_NET_RETRY_COUNT

CFG_HUSH_PARSER
Define this variable to enable the "hush" shell (from
Busybox) as command line interpreter, thus enabling
powerful command line syntax like
if...then...else...fi conditionals or `&&' and '||'
constructs ("shell scripts").
If undefined, you get the old, much simpler behaviour
with a somewhat smaller memory footprint.

This defines the secondary prompt string, which is
printed when the command interpreter needs more input
to complete a command. Usually "> ".

In the current implementation, the local variables
space and global environment variables space are
separated. Local variables are those you define by
simply typing `name=value'. To access a local
variable later on, you have write `$name' or
`${name}'; to execute the contents of a variable
directly type `$name' at the command prompt.

Defining this option allows to add some board-
specific code (calling a user-provided function
"show_boot_progress(int)") that enables you to show
the system's boot progress on some display (for
example, some LED's) on your board. At the moment,
the following checkpoints are implemented:

There are common interrupt_init() and timer_interrupt()
for all PPC archs. interrupt_init() calls interrupt_init_cpu()
for cpu specific initialization. interrupt_init_cpu()
should set decrementer_count to appropriate value. If
cpu resets decrementer automatically after interrupt
(ppc4xx) it should set decrementer_count to zero.
timer_interrupt() calls timer_interrupt_cpu() for cpu
specific handling. If board has watchdog / status_led
/ other_activity_monitor it works automatically from
general timer_interrupt().

In the target system modem support is enabled when a
specific key (key combination) is pressed during
power-on. Otherwise U-Boot will boot normally
(autoboot). The key_pressed() fuction is called from
board_init(). Currently key_pressed() is a dummy
function, returning 1 and thus enabling modem
initialization.

The following definitions that deal with the placement and management
of environment data (variable area); in general, we support the
following configurations:
- CFG_ENV_IS_IN_FLASH:
Define this if the environment is in flash memory.
a) The environment occupies one whole flash sector, which is
"embedded" in the text segment with the U-Boot code. This
happens usually with "bottom boot sector" or "top boot
sector" type flash chips, which have several smaller
sectors at the start or the end. For instance, such a
layout can have sector sizes of 8, 2x4, 16, Nx32 kB. In
such a case you would place the environment in one of the
4 kB sectors - with U-Boot code before and after it. With
"top boot sector" type flash chips, you would put the
environment in one of the last sectors, leaving a gap
between U-Boot and the environment.
- CFG_ENV_OFFSET:
Offset of environment data (variable area) to the
beginning of flash memory; for instance, with bottom boot
type flash chips the second sector can be used: the offset
for this sector is given here.
CFG_ENV_OFFSET is used relative to CFG_FLASH_BASE.
- CFG_ENV_ADDR:
This is just another way to specify the start address of
the flash sector containing the environment (instead of
CFG_ENV_OFFSET).
- CFG_ENV_SECT_SIZE:
Size of the sector containing the environment.
b) Sometimes flash chips have few, equal sized, BIG sectors.
In such a case you don't want to spend a whole sector for
the environment.
- CFG_ENV_SIZE:
If you use this in combination with CFG_ENV_IS_IN_FLASH
and CFG_ENV_SECT_SIZE, you can specify to use only a part
of this flash sector for the environment. This saves
memory for the RAM copy of the environment.
It may also save flash memory if you decide to use this
when your environment is "embedded" within U-Boot code,
since then the remainder of the flash sector could be used
for U-Boot code. It should be pointed out that this is
STRONGLY DISCOURAGED from a robustness point of view:
updating the environment in flash makes it always
necessary to erase the WHOLE sector. If something goes
wrong before the contents has been restored from a copy in
RAM, your target system will be dead.
- CFG_ENV_ADDR_REDUND
CFG_ENV_SIZE_REDUND

BE CAREFUL! Any changes to the flash layout, and some changes to the
source code will make it necessary to adapt <board>/u-boot.lds*
accordingly!
- CFG_ENV_IS_IN_NVRAM:
Define this if you have some non-volatile memory device
(NVRAM, battery buffered SRAM) which you want to use for the
environment.
- CFG_ENV_ADDR:
- CFG_ENV_SIZE:
These two #defines are used to determin the memory area you
want to use for environment. It is assumed that this memory
can just be read and written to, without any special
provision.
BE CAREFUL! The first access to the environment happens quite early
in U-Boot initalization (when we try to get the setting of for the
console baudrate). You *MUST* have mappend your NVRAM area then, or
U-Boot will hang.
Please note that even with NVRAM we still use a copy of the
environment in RAM: we could work on NVRAM directly, but we want to
keep settings there always unmodified except somebody uses "saveenv"
to save the current settings.
- CFG_ENV_IS_IN_EEPROM:
Use this if you have an EEPROM or similar serial access
device and a driver for it.
- CFG_ENV_OFFSET:
- CFG_ENV_SIZE:
These two #defines specify the offset and size of the
environment area within the total memory of your EEPROM.
- CFG_I2C_EEPROM_ADDR:
If defined, specified the chip address of the EEPROM device.
The default address is zero.
- CFG_EEPROM_PAGE_WRITE_BITS:
If defined, the number of bits used to address bytes in a
single page in the EEPROM device. A 64 byte page, for example
would require six bits.

2004-04-23 20:32:05 +00:00
- CFG_I2C_EEPROM_ADDR_OVERFLOW:
EEPROM chips that implement "address overflow" are ones
like Catalyst 24WC04/08/16 which has 9/10/11 bits of
address and the extra bits end up in the "chip address" bit
slots. This makes a 24WC08 (1Kbyte) chip look like four 256
byte chips.
Note that we consider the length of the address field to
still be one byte because the extra address bits are hidden
in the chip address.

- CFG_SPI_INIT_OFFSET
Defines offset to the initial SPI buffer area in DPRAM. The
area is used at an early stage (ROM part) if the environment
is configured to reside in the SPI EEPROM: We need a 520 byte
scratch DPRAM area. It is used between the two initialization
calls (spi_init_f() and spi_init_r()). A value of 0xB00 seems
to be a good choice since it makes it far enough from the
start of the data area as well as from the stack pointer.
Please note that the environment is read-only as long as the monitor
has been relocated to RAM and a RAM copy of the environment has been
created; also, when using EEPROM you will have to use getenv_r()
until then to read environment variables.
* Patch by Arun Dharankar, 24 Mar 2003: - add threads / scheduler example code * Add patches by Robert Schwebel, 31 Mar 2003: - add ctrl-c support for kermit download - align bdinfo output on ARM * Add CPU ID, version, and clock speed for INCA-IP
2003-03-31 16:34:49 +00:00
The environment is protected by a CRC32 checksum. Before the monitor
is relocated into RAM, as a result of a bad CRC you will be working
with the compiled-in default environment - *silently*!!! [This is
necessary, because the first environment variable we need is the
"baudrate" setting for the console - if we have a bad CRC, we don't
have any device yet where we could complain.]

Note:
On the MPC824X (or other systems that use the data
cache for initial memory) the address chosen for
CFG_INIT_RAM_ADDR is basically arbitrary - it must
point to an otherwise UNUSED address space between
the top of RAM and the start of the PCI space.

Building the Software:
======================
Building U-Boot has been tested in native PPC environments (on a
PowerBook G3 running LinuxPPC 2000) and in cross environments
(running RedHat 6.x and 7.x Linux on x86, Solaris 2.6 on a SPARC, and
NetBSD 1.5 on x86).
If you are not using a native PPC environment, it is assumed that you
have the GNU cross compiling tools available in your path and named
with a prefix of "powerpc-linux-". If this is not the case, (e.g. if
you are using Monta Vista's Hard Hat Linux CDK 1.2) you must change
the definition of CROSS_COMPILE in Makefile. For HHL on a 4xx CPU,
change it to:
CROSS_COMPILE = ppc_4xx-
Patch by Travis Sawyer, 30 Dec 2003: Add support for IBM PPC440GX. Multiple EMAC Ethernet devices, select MDI port based on enabled EMAC device. Add support for XES Inc <http://www.xes-inc.com> XPedite1000 440GX base PrPMC board.

sources you must configure U-Boot for one specific board type. This
is done by typing:
make NAME_config
where "NAME_config" is the name of one of the existing
configurations; the following names are supported:

Note: for some board special configuration names may exist; check if
additional information is available from the board vendor; for
instance, the TQM823L systems are available without (standard)
or with LCD support. You can select such additional "features"
when chosing the configuration, i. e.
make TQM823L_config
- will configure for a plain TQM823L, i. e. no LCD support
make TQM823L_LCD_config
- will configure for a TQM823L with U-Boot console on LCD
etc.
Finally, type "make all", and you should get some working U-Boot
images ready for download to / installation on your system:
- "u-boot.bin" is a raw binary image
- "u-boot" is an image in ELF binary format
- "u-boot.srec" is in Motorola S-Record format
Please be aware that the Makefiles assume you are using GNU make, so
for instance on NetBSD you might need to use "gmake" instead of
native "make".
If the system board that you have is not listed, then you will need
to port U-Boot to your hardware platform. To do this, follow these
steps:
1. Add a new configuration option for your board to the toplevel
"Makefile" and to the "MAKEALL" script, using the existing
entries as examples. Note that here and at many other places
boards and other names are listed in alphabetical sort order. Please
keep this order.
2. Create a new directory to hold your board specific code. Add any
files you need. In your board directory, you will need at least
the "Makefile", a "<board>.c", "flash.c" and "u-boot.lds".
3. Create a new configuration file "include/configs/<board>.h" for
your board
3. If you're porting U-Boot to a new CPU, then also create a new
directory to hold your CPU specific code. Add any files you need.
4. Run "make <board>_config" with your new name.
5. Type "make", and you should get a working "u-boot.srec" file
to be installed on your target system.
6. Debug and solve any problems that might arise.
[Of course, this last step is much harder than it sounds.]
Testing of U-Boot Modifications, Ports to New Hardware, etc.:
==============================================================
If you have modified U-Boot sources (for instance added a new board
or support for new devices, a new CPU, etc.) you are expected to
provide feedback to the other developers. The feedback normally takes
the form of a "patch", i. e. a context diff against a certain (latest
official or latest in CVS) version of U-Boot sources.
But before you submit such a patch, please verify that your modifi-
cation did not break existing code. At least make sure that *ALL* of
the supported boards compile WITHOUT ANY compiler warnings. To do so,
just run the "MAKEALL" script, which will configure and build U-Boot
for ALL supported system. Be warned, this will take a while. You can
select which (cross) compiler to use by passing a `CROSS_COMPILE'
environment variable to the script, i. e. to use the cross tools from
MontaVista's Hard Hat Linux you can type
CROSS_COMPILE=ppc_8xx- MAKEALL
or to build on a native PowerPC system you can type
CROSS_COMPILE=' ' MAKEALL

Environment Variables are set using "setenv", printed using
"printenv", and saved to Flash using "saveenv". Using "setenv"
without a value can be used to delete a variable from the
environment. As long as you don't save the environment you are
working with an in-memory copy. In case the Flash area containing the
environment is erased by accident, a default environment is provided.

autostart - if set to "yes", an image loaded using the "bootp",
"rarpboot", "tftpboot" or "diskboot" commands will
be automatically started (by internally calling
"bootm")
Add zero-copy ramdisk support (requires corresponding kernel support!)

If set to "no", a standalone image passed to the
"bootm" command will be copied to the load address
(and eventually uncompressed), but NOT be started.
This can be used to load and uncompress arbitrary
data.

Patch by Tolunay Orkun, 20 Apr 2004: - README update: add CONFIG_CSB272 and csb272_config - add descriptions for some MII/PHY options, CONFIG_I2CFAST, and i2cfast environment variable
2004-06-06 21:51:03 +00:00
i2cfast - (PPC405GP|PPC405EP only)
if set to 'y' configures Linux I2C driver for fast
mode (400kHZ). This environment variable is used in
initialization code. So, for changes to be effective
it must be saved and board must be reset.

initrd_high - restrict positioning of initrd images:
If this variable is not set, initrd images will be
copied to the highest possible address in RAM; this
is usually what you want since it allows for
maximum initrd size. If for some reason you want to
make sure that the initrd image is loaded below the
CFG_BOOTMAPSZ limit, you can set this environment
variable to a value of "no" or "off" or "0".
Alternatively, you can set it to a maximum upper
address to use (U-Boot will still check that it
does not overwrite the U-Boot stack and data).

For instance, when you have a system with 16 MB
RAM, and want to reserve 4 MB from use by Linux,
you can do this by adding "mem=12M" to the value of
the "bootargs" variable. However, now you must make
sure that the initrd image is placed in the first
12 MB as well - this can be done with

If you set initrd_high to 0xFFFFFFFF, this is an
indication to U-Boot that all addresses are legal
for the Linux kernel, including addresses in flash
memory. In this case U-Boot will NOT COPY the
ramdisk at all. This may be useful to reduce the
boot time on your system, but requires that this
feature is supported by your Linux kernel.

Although U-Boot should support any OS or standalone application
easily, the main focus has always been on Linux during the design of
U-Boot.

U-Boot includes many features that so far have been part of some
special "boot loader" code within the Linux kernel. Also, any
"initrd" images to be used are no longer part of one big Linux image;
instead, kernel and "initrd" are separate images. This implementation
serves several purposes:

- the same Linux kernel image can now be used with different "initrd"
images; of course this also means that different kernel images can
be run with the same "initrd". This makes testing easier (you don't
have to build a new "zImage.initrd" Linux image when you just
change a file in your "initrd"). Also, a field-upgrade of the
software is easier now.

U-Boot cannot save you from doing all the necessary modifications to
configure the Linux device drivers for use with your target hardware

Linux :-).

Just make sure your machine specific header file (for instance
include/asm-ppc/tqm8xx.h) includes the same definition of the Board
Information structure as we define in include/u-boot.h, and make
sure that your definition of IMAP_ADDR uses the same value as your
U-Boot configuration in CFG_IMMR.

With U-Boot, "normal" build targets like "zImage" or "bzImage" are
not used. If you use recent kernel source, a new build target
"uImage" will exist which automatically builds an image usable by
U-Boot. Most older kernels also have support for a "pImage" target,
which was introduced for our predecessor project PPCBoot and uses a
100% compatible format.
Example:
make TQM850L_config
make oldconfig
make dep
make uImage
The "uImage" build target uses a special tool (in 'tools/mkimage') to
encapsulate a compressed Linux kernel image with header information,
CRC32 checksum etc. for use with U-Boot. This is what we are doing:
* build a standard "vmlinux" kernel image (in ELF binary format):
* convert the kernel into a raw binary image:
${CROSS_COMPILE}-objcopy -O binary \
-R .note -R .comment \
-S vmlinux linux.bin
* compress the binary image:
gzip -9 linux.bin
* package compressed binary image for U-Boot:
mkimage -A ppc -O linux -T kernel -C gzip \
-a 0 -e 0 -n "Linux Kernel Image" \
-d linux.bin.gz uImage

2004-05-03 20:45:30 +00:00
The "mkimage" tool can also be used to create ramdisk images for use
with U-Boot, either separated from the Linux kernel image, or
combined into one file. "mkimage" encapsulates the images with a 64
byte header containing information about target architecture,
operating system, image type, compression method, entry points, time
stamp, CRC32 checksums, etc.
"mkimage" can be called in two ways: to verify existing images and
print the header information, or to build new images.
In the first form (with "-l" option) mkimage lists the information
contained in the header of an existing U-Boot image; this includes
checksum verification:

tools/mkimage -l image
-l ==> list image header information
The second form (with "-d" option) is used to build a U-Boot image
from a "data file" which is used as image payload:
tools/mkimage -A arch -O os -T type -C comp -a addr -e ep \
-n name -d data_file image
-A ==> set architecture to 'arch'
-O ==> set operating system to 'os'
-T ==> set image type to 'type'
-C ==> set compression type 'comp'
-a ==> set load address to 'addr' (hex)
-e ==> set entry point to 'ep' (hex)
-n ==> set image name to 'name'
-d ==> use image data from 'datafile'

Right now, all Linux kernels for PowerPC systems use the same load
address (0x00000000), but the entry point address depends on the
kernel version:

- 2.2.x kernels have the entry point at 0x0000000C,
- 2.3.x and later kernels have the entry point at 0x00000000.
So a typical call to build a U-Boot image would read:
-> tools/mkimage -n '2.4.4 kernel for TQM850L' \
> -A ppc -O linux -T kernel -C gzip -a 0 -e 0 \
> -d /opt/elsk/ppc_8xx/usr/src/linux-2.4.4/arch/ppc/coffboot/vmlinux.gz \
> examples/uImage.TQM850L

Data Size: 335725 Bytes = 327.86 kB = 0.32 MB
Load Address: 0x00000000

To verify the contents of the image (or check for corruption):
-> tools/mkimage -l examples/uImage.TQM850L
Image Name: 2.4.4 kernel for TQM850L
Created: Wed Jul 19 02:34:59 2000

NOTE: for embedded systems where boot time is critical you can trade
speed for memory and install an UNCOMPRESSED image instead: this
needs more space in Flash, but boots much faster since it does not
need to be uncompressed:
-> gunzip /opt/elsk/ppc_8xx/usr/src/linux-2.4.4/arch/ppc/coffboot/vmlinux.gz
-> tools/mkimage -n '2.4.4 kernel for TQM850L' \

Similar you can build U-Boot images from a 'ramdisk.image.gz' file
when your kernel is intended to use an initial ramdisk:
-> tools/mkimage -n 'Simple Ramdisk Image' \
> -A ppc -O linux -T ramdisk -C gzip \
> -d /LinuxPPC/images/SIMPLE-ramdisk.image.gz examples/simple-initrd

Installing a Linux Image:
-------------------------
To downloading a U-Boot image over the serial (console) interface,
you must convert the image to S-Record format:
objcopy -I binary -O srec examples/image examples/image.srec
The 'objcopy' does not understand the information in the U-Boot
image header, so the resulting S-Record file will be relative to
address 0x00000000. To load it to a given address, you need to
specify the target address as 'offset' parameter with the 'loads'
command.
Example: install the image to address 0x40100000 (which on the
TQM8xxL is in the first Flash bank):
=> erase 40100000 401FFFFF
.......... done
Erased 8 sectors

-----------
The "bootm" command is used to boot an application that is stored in
memory (RAM or Flash). In case of a Linux kernel image, the contents
of the "bootargs" environment variable is passed to the kernel as
parameters. You can check and modify this variable using the
"printenv" and "setenv" commands:
=> printenv bootargs
bootargs=root=/dev/ram
=> setenv bootargs root=/dev/nfs rw nfsroot=10.0.0.2:/LinuxPPC nfsaddrs=10.0.0.99:10.0.0.2

More About U-Boot Image Types:
------------------------------
U-Boot supports the following image types:
"Standalone Programs" are directly runnable in the environment
provided by U-Boot; it is expected that (if they behave
well) you can continue to work in U-Boot after return from
the Standalone Program.
"OS Kernel Images" are usually images of some Embedded OS which
will take over control completely. Usually these programs
will install their own set of exception handlers, device
drivers, set up the MMU, etc. - this means, that you cannot
expect to re-enter U-Boot except by resetting the CPU.
"RAMDisk Images" are more or less just data blocks, and their
parameters (address, size) are passed to an OS kernel that is
being started.
"Multi-File Images" contain several images, typically an OS
(Linux) kernel image and one or more data images like
RAMDisks. This construct is useful for instance when you want
to boot over the network using BOOTP etc., where the boot
server provides just a single image file, but you want to get
for instance an OS kernel and a RAMDisk image.
"Multi-File Images" start with a list of image sizes, each
image size (in bytes) specified by an "uint32_t" in network
byte order. This list is terminated by an "(uint32_t)0".
Immediately after the terminating 0 follow the images, one by
one, all aligned on "uint32_t" boundaries (size rounded up to
a multiple of 4 bytes).
"Firmware Images" are binary images containing firmware (like
U-Boot or FPGA images) which usually will be programmed to
flash memory.
"Script files" are command sequences that will be executed by
U-Boot's command interpreter; this feature is especially
useful when you configure U-Boot to use a real shell (hush)
as command interpreter.
Standalone HOWTO:
=================
One of the features of U-Boot is that you can dynamically load and
run "standalone" applications, which can use some resources of
U-Boot like console I/O functions or interrupt services.
Two simple examples are included with the sources:
"Hello World" Demo:
-------------------
'examples/hello_world.c' contains a small "Hello World" Demo
application; it is automatically compiled when you build U-Boot.
It's configured to run at address 0x00040004, so you can play with it
like that:
=> loads
## Ready for S-Record download ...
~>examples/hello_world.srec

argc = 7
argv[0] = "40004"
argv[1] = "Hello"
argv[2] = "World!"
argv[3] = "This"
argv[4] = "is"
argv[5] = "a"
argv[6] = "test."
argv[7] = "<NULL>"
Hit any key to exit ...
## Application terminated, rc = 0x0
Another example, which demonstrates how to register a CPM interrupt
handler with the U-Boot code, can be found in 'examples/timer.c'.
Here, a CPM timer is set up to generate an interrupt every second.
The interrupt service routine is trivial, just printing a '.'
character, but this is just a demo program. The application can be
controlled by the following keys:
? - print current values og the CPM Timer registers
b - enable interrupts and start timer
e - stop timer and disable interrupts
q - quit application
=> loads

Minicom warning:
================
Over time, many people have reported problems when trying to use the
"minicom" terminal emulation program for serial download. I (wd)
consider minicom to be broken, and recommend not to use it. Under
Unix, I recommend to use C-Kermit for general purpose use (and
especially for kermit binary protocol download ("loadb" command), and
use "cu" for S-Record download ("loads" command).
Nevertheless, if you absolutely want to use it try adding this
configuration to your "File transfer protocols" section:
Name Program Name U/D FullScr IO-Red. Multi
X kermit /usr/bin/kermit -i -l %l -s Y U Y N N
Y kermit /usr/bin/kermit -i -l %l -r N D Y N N
NetBSD Notes:
=============
Starting at version 0.9.2, U-Boot supports NetBSD both as host
(build U-Boot) and target system (boots NetBSD/mpc8xx).
Building requires a cross environment; it is known to work on
NetBSD/i386 with the cross-powerpc-netbsd-1.3 package (you will also
need gmake since the Makefiles are not compatible with BSD make).
Note that the cross-powerpc package does not install include files;
attempting to build U-Boot will fail because <machine/ansi.h> is
missing. This file has to be installed and patched manually:
# cd /usr/pkg/cross/powerpc-netbsd/include
# mkdir powerpc
# ln -s powerpc machine
# cp /usr/src/sys/arch/powerpc/include/ansi.h powerpc/ansi.h
# ${EDIT} powerpc/ansi.h ## must remove __va_list, _BSD_VA_LIST
Native builds *don't* work due to incompatibilities between native
and U-Boot include files.
Booting assumes that (the first part of) the image booted is a
stage-2 loader which in turn loads and then invokes the kernel
proper. Loader sources will eventually appear in the NetBSD source
tree (probably in sys/arc/mpc8xx/stand/u-boot_stage2/); in the
meantime, send mail to bruno@exet-ag.de and/or wd@denx.de for
details.
Implementation Internals:
=========================
The following is not intended to be a complete description of every
implementation detail. However, it should help to understand the
inner workings of U-Boot and make it easier to port it to custom
hardware.
Initial Stack, Global Data:
---------------------------
The implementation of U-Boot is complicated by the fact that U-Boot
starts running out of ROM (flash memory), usually without access to
system RAM (because the memory controller is not initialized yet).
This means that we don't have writable Data or BSS segments, and BSS
is not initialized as zero. To be able to get a C environment working
at all, we have to allocate at least a minimal stack. Implementation
options for this are defined and restricted by the CPU used: Some CPU
models provide on-chip memory (like the IMMR area on MPC8xx and
MPC826x processors), on others (parts of) the data cache can be
locked as (mis-) used as memory, etc.
Chris Hallinan posted a good summary of these issues to the
u-boot-users mailing list:
Subject: RE: [U-Boot-Users] RE: More On Memory Bank x (nothingness)?
From: "Chris Hallinan" <clh@net1plus.com>

...
Correct me if I'm wrong, folks, but the way I understand it
is this: Using DCACHE as initial RAM for Stack, etc, does not
require any physical RAM backing up the cache. The cleverness
is that the cache is being used as a temporary supply of
necessary storage before the SDRAM controller is setup. It's
beyond the scope of this list to expain the details, but you
can see how this works by studying the cache architecture and
operation in the architecture and processor-specific manuals.
OCM is On Chip Memory, which I believe the 405GP has 4K. It
is another option for the system designer to use as an
initial stack/ram area prior to SDRAM being available. Either
option should work for you. Using CS 4 should be fine if your
board designers haven't used it for something that would
cause you grief during the initial boot! It is frequently not
used.
CFG_INIT_RAM_ADDR should be somewhere that won't interfere
with your processor/board/system design. The default value
you will find in any recent u-boot distribution in
Walnut405.h should work for you. I'd set it to a value larger
than your SDRAM module. If you have a 64MB SDRAM module, set
it above 400_0000. Just make sure your board has no resources
that are supposed to respond to that address! That code in
start.S has been around a while and should work as is when
you get the config right.
-Chris Hallinan
DS4.COM, Inc.
It is essential to remember this, since it has some impact on the C
code for the initialization procedures:
* Initialized global data (data segment) is read-only. Do not attempt
to write it.
* Do not use any unitialized global data (or implicitely initialized
as zero data - BSS segment) at all - this is undefined, initiali-
zation is performed later (when relocating to RAM).
* Stack space is very limited. Avoid big data buffers or things like
that.
Having only the stack as writable memory limits means we cannot use
normal global data to share information beween the code. But it
turned out that the implementation of U-Boot can be greatly
simplified by making a global data structure (gd_t) available to all
functions. We could pass a pointer to this data as argument to _all_
functions, but this would bloat the code. Instead we use a feature of
the GCC compiler (Global Register Variables) to share the data: we
place a pointer (gd) to the global data into a register which we
reserve for this purpose.
When choosing a register for such a purpose we are restricted by the
relevant (E)ABI specifications for the current architecture, and by
GCC's implementation.
For PowerPC, the following registers have specific use:
R1: stack pointer
R2: TOC pointer
R3-R4: parameter passing and return values
R5-R10: parameter passing
R13: small data area pointer
R30: GOT pointer
R31: frame pointer
(U-Boot also uses R14 as internal GOT pointer.)
==> U-Boot will use R29 to hold a pointer to the global data
Note: on PPC, we could use a static initializer (since the
address of the global data structure is known at compile time),
but it turned out that reserving a register results in somewhat
smaller code - although the code savings are not that big (on
average for all boards 752 bytes for the whole U-Boot image,
624 text + 127 data).
On ARM, the following registers are used:
R0: function argument word/integer result
R1-R3: function argument word
R9: GOT pointer
R10: stack limit (used only if stack checking if enabled)
R11: argument (frame) pointer
R12: temporary workspace
R13: stack pointer
R14: link register
R15: program counter
==> U-Boot will use R8 to hold a pointer to the global data
Memory Management:
------------------
U-Boot runs in system state and uses physical addresses, i.e. the
MMU is not used either for address mapping nor for memory protection.
The available memory is mapped to fixed addresses using the memory
controller. In this process, a contiguous block is formed for each
memory type (Flash, SDRAM, SRAM), even when it consists of several
physical memory banks.
U-Boot is installed in the first 128 kB of the first Flash bank (on
TQM8xxL modules this is the range 0x40000000 ... 0x4001FFFF). After
booting and sizing and initializing DRAM, the code relocates itself
to the upper end of DRAM. Immediately below the U-Boot code some
memory is reserved for use by malloc() [see CFG_MALLOC_LEN
configuration setting]. Below that, a structure with global Board
Info data is placed, followed by the stack (growing downward).
Additionally, some exception handler code is copied to the low 8 kB
of DRAM (0x00000000 ... 0x00001FFF).
So a typical memory configuration with 16 MB of DRAM could look like
this:
0x0000 0000 Exception Vector code
:
0x0000 1FFF
0x0000 2000 Free for Application Use
:
:
:
:
0x00FB FF20 Monitor Stack (Growing downward)
0x00FB FFAC Board Info Data and permanent copy of global data
0x00FC 0000 Malloc Arena
:
0x00FD FFFF
0x00FE 0000 RAM Copy of Monitor Code
... eventually: LCD or video framebuffer
... eventually: pRAM (Protected RAM - unchanged by reset)
0x00FF FFFF [End of RAM]

In the reset configuration, U-Boot starts at the reset entry point
(on most PowerPC systens at address 0x00000100). Because of the reset
configuration for CS0# this is a mirror of the onboard Flash memory.
To be able to re-map memory U-Boot then jumps to its link address.
To be able to implement the initialization code in C, a (small!)
initial stack is set up in the internal Dual Ported RAM (in case CPUs
which provide such a feature like MPC8xx or MPC8260), or in a locked
part of the data cache. After that, U-Boot initializes the CPU core,
the caches and the SIU.
Next, all (potentially) available memory banks are mapped using a
preliminary mapping. For example, we put them on 512 MB boundaries
(multiples of 0x20000000: SDRAM on 0x00000000 and 0x20000000, Flash
on 0x40000000 and 0x60000000, SRAM on 0x80000000). Then UPM A is
programmed for SDRAM access. Using the temporary configuration, a
simple memory test is run that determines the size of the SDRAM
banks.
When there is more than one SDRAM bank, and the banks are of
different size, the largest is mapped first. For equal size, the first
bank (CS2#) is mapped first. The first mapping is always for address
0x00000000, with any additional banks following immediately to create
contiguous memory starting from 0.
Then, the monitor installs itself at the upper end of the SDRAM area
and allocates memory for use by malloc() and for the global Board
Info data; also, the exception vector code is copied to the low RAM
pages, and the final stack is set up.
Only after this relocation will you have a "normal" C environment;
until that you are restricted in several ways, mostly because you are
running from ROM, and because the code will have to be relocated to a
new address in RAM.

When adding new features, these should compile conditionally only
(using #ifdef), and the resulting code with the new feature
disabled must not need more memory than the old code without your
modification.
