Previously we didn't support upload/download larger than available
memory. This is pretty bad when you have to update your root filesystem
for example.
This patch removes that limitation (and the crashes when you transfered
any file larger than 4MB) by making raw image writes be done in chunks
and making file maximum size be configurable.
The sequence number is a 16 bit counter; make sure we handle rollover
correctly. This fixes the wrong transfers for large (> 256MB) images.
Also utilize a variable to handle initialization, so that we don't rely
on just the counter sent by the host.

The omap5_uevm platform has eMMC, and it makes sense to say that our
default env storage shall reside there. Other platforms may not, so
move this choice to the EVM config. In addition, we should provide some
way to partition the flash for later usage, so take advantage of the GPT
partition table support code and allow that to be setup with some
reasonable defaults.

For production systems it is better to use script images since
they are protected by checksums and carry valuable information
like name and timestamp. Also, you can't validate the content
passed to env import.
But for development, it is easier to use the env import command and
plain text files instead of script-images.
Since both OMAP5evm/uevm boards are used primarily for development,
we allow U-Boot to load env var from a text file in case that an
boot.scr script-image is not present.
The variable uenvcmd (if existent) will be executed (using run) after
uEnv.txt was loaded. If uenvcmd doesn't exist the default boot sequence
will be started.

The omap2420-h4 board is using a RAM based address as the linker
location for code. This is causing several problems when attempting
to run the latest u-boot code base on this board from flash. Update
the default linker location for code to be in NOR flash. Please note
that OMAP maps the NOR flash to address 0x08000000 by default and so
use this as the default address for the NOR flash.
Also remove legacy code that attempts to calculate where in flash the
sdata structure, that holds the memory interface configuration data,
is located. By changing the default linker location for code to flash
this is no longer necessary.

Maximum bus width supported by some i.MX6 boards is not 8bit like
others. In case where both host controller and card support 8bit transfers,
they agree to communicate on 8bit interface while some boards support only 4bit interface.
Due to this reason the mmc 8bit default mode fails on these boards. To rectify this,
define maximum bus width supported by these boards (4bit). If max_bus_width is not
defined, it is 0 by default and 8bit width support will be enabled in host
capabilities otherwise host capabilities are modified accordingly.

This commit is based on that patch from aaron.williams@caviumnetworks.com
with same commit title. pulled the same code changes into current u-boot tree.
http://patchwork.ozlabs.org/patch/140863/http://lists.denx.de/pipermail/u-boot/2011-April/089606.html
This patch corrects the addresses used when working with Spansion/AMD FLASH chips.
Addressing for 8 and 16 bits is almost identical except in the 16-bit case the
LSB of the address is always 0. The confusion arose because the addresses
in the datasheet for 16-bit mode are word addresses but this code assumed it was
byte addresses.
I have only been able to test this on our Octeon boards which use either an 8-bit
or 16-bit bus. I have not tested the case where there's an 8-bit part on a 16-bit
bus.
This patch also adds some delays as suggested by Spansion.
If a part can be both 8 and 16-bits, it forces it to work in 8-bit mode if an
8-bit bus is detected.
Apart from the pulled changes, fixed few minor code cleanups and tested
on 256M29EW, 512M29EW flashes.

When running this command the menu will be assembled as defined

We decided to used unsigned int here, rather than unsigned long. But
for the generic global_data it is still unsigned long. So change it
over.

These boards define CONFIG_LAST_STAGE_INIT and CONFIG_BOARD_EARLY_INIT_R
but these options are not available on ARM. Move them into the powerpc
common file instead.
This change affects: km_kirkwood_pci, mgcoge3un, kmnusa, kmcoge5un,
km_kirkwood and portl2.

It starts up the console, DRAM, performs relocation and then jumps
to post-relocation init.

These functions are only available for powerpc and are not declared in a
header file. We want to use the rest function in two places (board_f and
board_r), so declare the functions in watchdog.h.
