3fa4977a9e Revert "Add board_pre_console_putc to deal with early console output"
This reverts commit 295d3942b8.

It turns that this really doesn't work very nicely. Instead we should
have a pre-console panic function so that we know that further execution
is impossible and we don't need to worry about trampling on UARTs, etc.

3a608ca01d bootstage: Implement core microsecond boot time measurement
This defines the basics of a new boot time measurement feature. This allows
logging of very accurate time measurements as the boot proceeds, by using
an available microsecond counter.

To enable the feature, define CONFIG_BOOTSTAGE in your board config file.
Also available is CONFIG_BOOTSTAGE_REPORT which will cause a report to be
printed just before handing off to the OS.

Most IDs are not named at this stage. For that I would first like to
renumber them all.

fa34f6b25b common/image.c: align usage of fdt_high with initrd_high
The commit message of a28afca (Add uboot "fdt_high" enviroment variable)
states that fdt_high behaves similarly to the existing initrd_high.
But fdt_high actually has an outstanding difference from initrd_high.
The former specifies the start address, while the later specifies the
end address.

As fdt_high and initrd_high will likely be used together, it'd be nice
to have them behave same.  The patch changes the behavior of fdt_high
to have it aligned with initrd_high.

The document of fdt_high in README is updated with an example to
demonstrate the usage of this environment variable.

046a37bd53 Add safe vsnprintf and snprintf library functions
From: Sonny Rao <sonnyrao@chromium.org>

These functions are useful in U-Boot because they allow a graceful failure
rather than an unpredictable stack overflow when printf() buffers are
exceeded.

Mostly copied from the Linux kernel. I copied vscnprintf and
scnprintf so we can change printf and vprintf to use the safe
implementation but still return the correct values.

295d3942b8 Add board_pre_console_putc to deal with early console output
This patch adds support for console output before the console is inited.
The main purpose of this is to deal with a very early panic() which would
otherwise cause a silent hang.

A new board_pre_console_putc() function is added to the board API. If
provided by the board it will be called in the event of console output
before the console is ready. This function should turn on all UARTs and
spray the character out if it possibly can.

The feature is controlled by a new CONFIG_PRE_CONSOLE_PUTC option.

5e1247247b Introduce generic TPM support in u-boot
TPM (Trusted Platform Module) is an integrated circuit and
software platform that provides computer manufacturers with the
core components of a subsystem used to assure authenticity,
integrity and confidentiality.

This driver supports version 1.2 of the TCG (Trusted Computing
Group) specifications.

The TCG specification defines several so called localities in a
TPM chip, to be controlled by different software layers. When
used on a typical x86 platform during the firmware phase, only
locality 0 can be accessed by the CPU, so this driver even while
supporting the locality concept presumes that only locality zero
is used.

This implementation is loosely based on the article "Writing a
TPM Device Driver" published on http://ptgmedia.pearsoncmg.com

Compiling this driver with DEBUG defined will generate trace of
all accesses to TMP registers.

This driver has been tested and is being used in three different
functional ChromeOS machines (Pinetrail and Sandy Bridge Intel
chipsets) all using the same Infineon SLB 9635 TT 1.2 device.

A u-boot cli command allowing access to the TPM was also
implemented and is being submitted as a second patch.

f2717b47ea powerpc/85xx: clean up and document the QE/FMAN microcode macros
Several macros are used to identify and locate the microcode binary image
that U-boot needs to upload to the QE or Fman.  Both the QE and the Fman
use the QE Firmware binary format to package their respective microcode data,
which is why the same macros are used for both.  A given SOC will only have
a QE or an Fman, so this is safe.

Unfortunately, the current macro definition and usage has inconsistencies.
For example, CONFIG_SYS_FMAN_FW_ADDR was used to define the address of Fman
firmware in NOR flash, but CONFIG_SYS_QE_FW_IN_NAND contains the address
of NAND.  There's no way to know by looking at a variable how it's supposed
to be used.

In the future, the code which uploads QE firmware and Fman firmware will
be merged.

reason is 062fe7d332 new define MAX_PHY.
This is set to 3! I get on this board 5 active phys, so
this leads in wrong memory writes ...

so I changed:

- define CONFIG_SYS_DAVINCI_EMAC_PHY_COUNT to set

- print an error message if more then MAX_PHYs are

- changed printf() in debug_emac()

ce5207e191 e1000: Allow direct access to the E1000 SPI EEPROM device
As a part of the manufacturing process for some of our custom hardware,
we are programming the EEPROMs attached to our Intel 82571EB controllers
from software using U-Boot and Linux.

This code provides several conditionally-compiled features to assist in
our manufacturing process:

  CONFIG_CMD_E1000:
    This is a basic "e1000" command which allows querying the controller
    and (if other config options are set) performing EEPROM programming.
    In particular, with CONFIG_E1000_SPI this allows you to display a
    hex-dump of the EEPROM, copy to/from main memory, and verify/update
    the software checksum.

  CONFIG_E1000_SPI_GENERIC:
    Build a generic SPI driver providing the standard U-Boot SPI driver
    interface.  This allows commands such as "sspi" to access the bus
    attached to the E1000 controller.  Additionally, some E1000 chipsets
    can support user data in a reserved space in the E1000 EEPROM which
    could be used for U-Boot environment storage.

  CONFIG_E1000_SPI:
    The core SPI access code used by the above interfaces.

For example, the following commands allow you to program the EEPROM from
a USB device (assumes CONFIG_E1000_SPI and CONFIG_CMD_E1000 are enabled):
  usb start
  fatload usb 0 $loadaddr 82571EB_No_Mgmt_Discrete-LOM.bin
  e1000 0 spi program $loadaddr 0 1024
  e1000 0 spi checksum update

Please keep in mind that the Intel-provided .eep files are organized as
16-bit words.  When converting them to binary form for programming you
must byteswap each 16-bit word so that it is in little-endian form.

This means that when reading and writing words to the SPI EEPROM, the
bit ordering for each word looks like this on the wire:

  Time >>>
------------------------------------------------------------------
  ... [7, 6, 5, 4, 3, 2, 1, 0, 15, 14, 13, 12, 11, 10, 9, 8], ...
------------------------------------------------------------------
  (MSB is 15, LSB is 0).

This new option allows U-Boot to embed a binary device tree into its image
to allow run-time control of peripherals. This device tree is for U-Boot's

The device tree compiler output should be placed in the $(obj)

invoked from the directory where the .dtb file is located and
given the input file name without the path.

80421fcc3e MIPS: Ingenic XBurst Jz4740 processor support
Jz4740 is a multimedia application processor targeting for mobile
devices like e-Dictionary, eBook, portable media player (PMP) and
GPS navigator.  Jz4740 is powered by Ingenic 360 MHz XBurst CPU core
(JzRISC), in which RISC/SIMD/DSP hybrid instruction set architecture
provides high integration, high performance and low power consumption.

JzRISC incorporated in Jz4740 is the advanced and power-efficient
32-bit RISC core, compatible with MIPS32, with 16K I-Cache and 16K
D-Cache, and can operate at speeds up to 400 MHz.

On-chip modules such as LCD controller, embedded audio codec, multi-
channel SAR-ADC, AC97/I2S controller and camera I/F offer a rich
suite of peripherals for multimedia application.  NAND controller
(SLC/MLC), USB (host 1.1 and device 2.0), UART, I2C, SPI, etc. are
also available.

For more info about Ingenic XBurst Jz4740:
  http://en.ingenic.cn/eng/
  http://www.linux-mips.org/wiki/Ingenic

This patch introduces XBurst CPU support in U-Boot.  It's compatible
with MIPS32, but requires a bit different cache maintenance, timer
routines, and boot mechanism using USB boot tool, so XBurst support
can go into a separate new home, cpu/xburst/.

6f5e1dc531 powerpc/8xxx: Add support for interactive DDR programming interface
Interactive DDR debugging provides a user interface to view and modify SPD,
DIMM parameters, board options and DDR controller registers before DDR is
initialized. With this feature, developers can fine-tune DDR for board
bringup and other debugging without frequently having to reprogram the flash.

To enable this feature, define CONFIG_FSL_DDR_INTERACTIVE in board header
file and set an environment variable to activate it. Syntax:

setenv ddr_interactive on

After reset, U-boot prompts before initializing DDR controllers
FSL DDR>

The available commands are
print      print SPD and intermediate computed data
reset      reboot machine
recompute  reload SPD and options to default and recompute regs
edit       modify spd, parameter, or option
compute    recompute registers from current next_step to end
next_step  shows current next_step
help       this message
go         program the memory controller and continue with u-boot

The first command should be "compute", which reads data from DIMM SPDs and
board options, performs the calculation then stops before setting DDR
controller. A user can use "print" and "edit" commands to view and modify
anything. "Go" picks up from current step with any modification and
compltes the calculation then enables the DDR controller to continue u-boot.
"Recompute" does it over from fresh reading.

9558b48af0 console: Implement pre-console buffer
Allow redirection of console output prior to console initialisation to a
temporary buffer.

To enable this functionality, the board (or arch) must define:
 - CONFIG_PRE_CONSOLE_BUFFER - Enable pre-console buffer
 - CONFIG_PRE_CON_BUF_ADDR - Base address of pre-console buffer
 - CONFIG_PRE_CON_BUF_SZ - Size of pre-console buffer (in bytes)

The pre-console buffer will buffer the last CONFIG_PRE_CON_BUF_SZ bytes
Any earlier characters are silently dropped.

e46fedfeb2 powerpc/85xx: introduce and document CONFIG_SYS_CCSRBAR macros
Introduce the CONFIG_SYS_CCSRBAR_PHYS_HIGH and CONFIG_SYS_CCSRBAR_PHYS_LOW
macros, which contain the high and low portions of CONFIG_SYS_CCSRBAR_PHYS.
This is necessary for the assembly-language code that relocates CCSR, since
the assembler does not understand 64-bit constants.

CONFIG_SYS_CCSRBAR_PHYS is automatically defined from the
CONFIG_SYS_CCSRBAR_PHYS_HIGH and CONFIG_SYS_CCSRBAR_PHYS_LOW macros, so it
should not be defined in a board header file.  Similarly,
CONFIG_SYS_CCSRBAR_DEFAULT is defined for each SOC in config_mpc85xx.h, so
it should also not be defined in the board header file.

CONFIG_SYS_CCSR_DO_NOT_RELOCATE is a "short-cut" macro that guarantees that
CONFIG_SYS_CCSRBAR_PHYS is set to the same value as CONFIG_SYS_CCSRBAR_DEFAULT,
and so CCSR will not be relocated.

Since CONFIG_SYS_CCSRBAR_DEFAULT is locked to a fixed value, multi-stage U-Boot
builds (e.g. NAND) are required to relocate CCSR only during the last stage
(i.e. the "real" U-Boot).  All other stages should define
CONFIG_SYS_CCSR_DO_NOT_RELOCATE to ensure that CCSR is not relocated.

README is updated with descriptions of all the CONFIG_SYS_CCSRBAR_xxx macros.

IDE-PCI controller, some additional registers and commands access is required
during CMD/DATA I/O. Hence a configuration "CONFIG_IDE_AHB" in cmd_ide.c is

ba8e76bd49 powerpc: use 'video-mode' environment variable to configure DIU
Use the 'video-mode' environment variable (for Freescale chips that have a
DIU display controller) to designate the full video configuration.  Previously,
the DIU driver used the 'monitor' variable, and it was used only to determine
the output video port.

The old definition of the "monitor" environment variable only determines
which video port to use for output.  This variable was set to a number (0,
1, or sometimes 2) to specify a DVI, LVDS, or Dual-LVDS port.  The
resolution was hard-coded into board-specific code.  The Linux command-line
arguments needed to be hard-coded to the proper video definition string.

a000b7950d common: add a grepenv command
u-boot environments, esp. when boards are shared across multiple
users, can get pretty large and time consuming to visually parse.
The grepenv command this patch adds can be used in lieu of printenv
to facilitate searching.  grepenv works like printenv but limits
its output only to environment strings (variable name and value
pairs) that match the user specified substring.

the following examples are on a board with a 5313 byte environment
that spans multiple screen pages:

Example 1:  summarize ethernet configuration:

=> grepenv eth TSEC
etact=FM1@DTSEC2
eth=FM1@DTSEC4
ethact=FM1@DTSEC2
eth1addr=00:E0:0C:00:8b:01
eth2addr=00:E0:0C:00:8b:02
eth3addr=00:E0:0C:00:8b:03

=>

Example 2: detect unused env vars:

=> grepenv etact
etact=FM1@DTSEC2
=>

Example 3: reveal hardcoded variables; e.g., for fdtaddr:

=> grepenv fdtaddr
fdtaddr=c00000
nfsboot=setenv bootargs root=/dev/nfs rw nfsroot=$serverip:$rootpath ip=$ipaddr:$serverip:$gatewayip:$netmask:$hostname:$netdev:off console=$consoledev,$baudrate $othbootargs;tftp $loadaddr $bootfile;tftp $fdtaddr $fdtfile;bootm $loadaddr - $fdtaddr

=> grep $fdtaddr
fdtaddr=c00000
my_boot=bootm 0x40000000 0x41000000 0x00c00000
my_dtb=tftp 0x00c00000 $prefix/p4080ds.dtb

=>

This patch also enables the grepenv command by default on
corenet_ds based boards (and repositions the DHCP command
entry to keep the list sorted).

defaults to getenv_bootm_size(), which in turn defaults to the size of
RAM.

getenv_bootm_mapsize() can also be overridden with a "bootm_mapsize"

7d3053fbf1 powerpc: clean up DIU macro definitions for Freescale reference boards
Clean up the macro defintions used to enable DIU (video) support on the
MPC8610HPCD and the MPC5121ADS so that they look more like the P1022DS,
which is newer.  Add software cursor support to all three boards.

Also document the CONFIG_FSL_DIU_FB in the README.

cf946c6d09 mv: seperate kirkwood and armada from common setting
Since there are lots of difference between kirkwood and armada series,
it is better to seperate them but still keep the most common file
shared by all marvell platform in the mv-common configure file.

This patch move the kirkwood only driver definitoin in mv-common to
the <soc_name>/config.h.

This patch is tested with compilation for armada100 and guruplug.

a09b9b68d4 powerpc/8xxx: Refactor SRIO initialization into common code
Moved the SRIO init out of corenet_ds and into common code for
8xxx/QorIQ processors that have SRIO.  We mimic what we do with PCIe
controllers for SRIO.

We utilize the fact that SRIO is over serdes to determine if its
configured or not and thus can setup the LAWs needed for it dynamically.

We additionally update the device tree (to remove the SRIO nodes) if the
board doesn't have SRIO enabled.

Introduced the following standard defines for board config.h:

CONFIG_SYS_SRIO - Chip has SRIO or not
CONFIG_SRIO1 - Board has SRIO 1 port available
CONFIG_SRIO2 - Board has SRIO 2 port available

(where 'n' is the port #)
CONFIG_SYS_SRIOn_MEM_VIRT - virtual address in u-boot
CONFIG_SYS_SRIOn_MEM_PHYS - physical address (for law setup)
CONFIG_SYS_SRIOn_MEM_SIZE - size of window (for law setup)

[ These mimic what we have for PCI and PCIe controllers ]

5dec49ca22 pca953x: support 16-pin devices
This adds support for for the PCA9535/PCA9539 family of gpio devices which
have 16 output pins.

To let the driver know which devices are 16-pin it is necessary to define
CONFIG_SYS_I2C_PCA953X_WIDTH in your board config file. This is used to
create an array of {chip, ngpio} tuples that are used to determine the
width of a particular chip. For backwards compatibility it is assumed that
any chip not defined in CONFIG_SYS_I2C_PCA953X_WIDTH has 8 pins.

e03f316974 Drop support for CONFIG_SKIP_RELOCATE_UBOOT
For ARM systems, before ELF relocation was introduced,
CONFIG_SKIP_RELOCATE_UBOOT coul be used to prevent *COPYING* the
U-Boot image from whereever it was loaded to it's link address
(CONFIG_SYS_TEXT_BASE).  The name was badly chosen, as no relocation
was performed at all, it was just a memcpy().

With ELF relocation, this does not work like that any more, and
related boards need to be fixed anyway.  So don't keep this relict any
longer.

553f09823c Rename CONFIG_SYS_INIT_RAM_END into CONFIG_SYS_INIT_RAM_SIZE
CONFIG_SYS_INIT_RAM_END was a misnomer as it suggests this might be
some end address; to make the meaning more clear we rename it into
CONFIG_SYS_INIT_RAM_SIZE

No other code changes are performed in this patch, only minor editing
of white space (due to the changed length) and the comments was done,
where noticed.

Note that the code for the PATI and cmi_mpc5xx board configurations
looks seriously broken.  Last known maintainers on Cc:

14d0a02a16 Rename TEXT_BASE into CONFIG_SYS_TEXT_BASE
The change is currently needed to be able to remove the board
configuration scripting from the top level Makefile and replace it by
a simple, table driven script.

Moving this configuration setting into the "CONFIG_*" name space is
also desirable because it is needed if we ever should move forward to
a Kconfig driven configuration system.
