A negative value of CONFIG_ENV_OFFSET is treated as a backwards offset
from the end of the eMMC device/partition, rather than a forwards offset
from the start.
This is useful when a single board may be stuffed with different eMMC
devices, each of which has a different capacity, and you always want the
environment to be stored at the very end of the device (or eMMC boot
partition for example).
One example of this case is NVIDIA's Ventana reference board.

This patch adds support to both Faraday FUSBH200 and FOTG210,
the differences between Faraday EHCI and standard EHCI are
listed bellow:
1. The PORTSC starts at 0x30 instead of 0x44.
2. The CONFIGFLAG(0x40) is not only un-implemented, and
also has its address space removed.
3. Faraday EHCI is a TDI design, but it doesn't
compatible with the general TDI implementation
found at both U-Boot and Linux.
4. The ISOC descriptors differ from standard EHCI in
several ways. But since U-boot doesn't support ISOC,
we don't have to worry about that.

Some ARM compilers may emit code that makes unaligned accesses when
faced with constructs such as:

Replace this with a strcpy() call instead to avoid this. strcpy() is
used here, rather than replacing all usage of the mac variable with the
string itself, since the loop itself sprintf()s to the variable each
iteration, so strcpy() is doing basically the same thing.

simple-framebuffer is a new device tree binding that describes a pre-

describe the framebuffer format that U-Boot is using.
This will be immediately used by the Raspberry Pi board in U-Boot, and

Much of the image code uses addresses as ulongs and pointers interchangeably,

This doesn't work with sandbox, which has a U-Boot RAM buffer which is

Adjust the cost so that translating from a U-Boot address to a pointer uses
map_sysmem(). This allows bootm to work correctly on sandbox.

Add "setexpr name gsub r s [t]" and "setexpr name sub r s [t]"
commands which implement substring matching for the regular
expression <r> in the string <t>, and substitution of the string <s>.
The result is assigned to the environment variable <name>. If <t> is
not supplied, the previous value of <name> is used instead. "gsub"
performs global substitution, while "sub" will replace only the first
substring.
Both commands are closely modeled after the gawk functions with the
same names.
Examples:
- Generate broadcast address by substituting the last two numbers of
the IP address by "255.255":
=> print ipaddr
ipaddr=192.168.1.104
=> setexpr broadcast sub "(.*\\.).*\\..*" "\\1255.255" $ipaddr
broadcast=192.168.255.255
- Depending on keyboard configuration (German vs. US keyboard) a
barcode scanner may initialize the MAC address as C0:E5:4E:02:06:DC
or as C0>E5>4E>02>06>DC. Make sure we always have a correct value:
=> print ethaddr
ethaddr=C0>E5>4E>02>06>DC
=> setexpr ethaddr gsub > :
ethaddr=C0:E5:4E:02:06:DC
- Do the same, but substitute one step at a time in a loop until no
futher matches:
=> setenv ethaddr C0>E5>4E>02>06>DC
=> while setexpr ethaddr sub > :
> do
> echo -----
> done
ethaddr=C0:E5>4E>02>06>DC
-----
ethaddr=C0:E5:4E>02>06>DC
-----
ethaddr=C0:E5:4E:02>06>DC
-----
ethaddr=C0:E5:4E:02:06>DC
-----
ethaddr=C0:E5:4E:02:06:DC

With sandbox it is tricky to add an FDT to the image at build time (or
later) since we build an ELF file, not a plain binary, and the address
space of the whole U-Boot is not accessible in the emulated memory map
of sandbox.
Sandbox can read files directly from the host, though, so add an option
to read an FDT from a host file on start-up.

Sometimes it might make sense to verify the written data to NOR flash.
This patch adds this feature. To enable this verify-after-write, you
need to define CONFIG_FLASH_VERIFY in your board config header.
Please note that this option is useless in nearly all cases,
since such flash programming errors usually are detected earlier
while unprotecting/erasing/programming. Please only enable
this option if you really know what you are doing.

Currently x86 has its own means of managing the global data and board data
(bd_t), and this code resides in start.S. With generic board, we need to
ensure that we leave this alone - i.e. don't clear it as we do on other
archs.
This fixes a problem where the memory init data is cleared which causes
the video driver to operate very slowly.
Signed-off-by: Simon Glass <sjg@chromium.org>
The intention of the memory init code is that it should work the same with
CONFIG_SYS_GENERIC_BOARD and without. This is tricky because dram_init()
is called prior to relocation with generic board (matching other archs)
and after relocation without generic board.
Adjust the init sequence so that dram_init() is not called in the generic
board case, which seems like the easiest fix for now. Also ensure that
relocation addresses are still calculated.

TPM command library implements a subset of TPM commands defined in TCG
Main Specification 1.2 that are useful for implementing secure boot.
More TPM commands could be added out of necessity.
You may exercise these commands through the 'tpm' command. However, the
raw TPM commands are too primitive for writing secure boot in command
interpreter scripts; so the 'tpm' command also provides helper functions
to make scripting easier.
For example, to define a counter in TPM non-volatile storage and
initialize it to zero:
$ tpm init
$ tpm startup TPM_ST_CLEAR
$ tpm nv_define d 0x1001 0x1
$ tpm nv_write d 0x1001 0
And then increment the counter by one:
$ tpm nv_read d 0x1001 i
$ setexpr.l i $i + 1
$ tpm nv_write d 0x1001 $i

We make these two functions take a size_t pointer to how much space
was used on NAND to read or write the buffer (when reads/writes happen)
so that bad blocks can be accounted for. We also make them take an
loff_t limit on how much data can be read or written. This means that
we can now catch the case of when writing to a partition would exceed
the partition size due to bad blocks. To do this we also need to make
check_skip_len count not just complete blocks used but partial ones as
well. All callers of nand_(read|write)_skip_bad are adjusted to call
these with the most sensible limits available.

When an LCD driver is actually driving a regular external display, e.g.
an HDMI monitor, the display resolution might not be known until the
display controller has initialized, i.e. during lcd_ctrl_init(). However,
lcd.c calculates lcd_line_length before calling this function, thus
relying on a hard-coded resolution in struct panel_info.
Instead, defer this calculation until after lcd_ctrl_init() has had the
chance to dynamically determine the resolution. This needs to happen
before lcd_clear(), since the value is used there.
grep indicates that no code outside lcd.c uses this lcd_line_length; in
particular, no lcd_ctrl_init() implementations read it.

To avoid incompatible changes of the interface, we now check the last
