The code handles relocation entries with the
following relocation types only:
mips32: R_MIPS_REL32
mips64: R_MIPS_REL+R_MIPS_64
xburst: R_MIPS_REL32
Other relocation entries are skipped without
processing. The code must be extended if other
relocation types must be supported.

Add driver for tegra SPI "SLINK" style driver. This controller is
similar to the tegra20 SPI "SFLASH" controller. The difference is
that the SLINK controller is a genernal purpose SPI controller and the
SFLASH controller is special purpose and can only talk to FLASH
devices. In addition there are potentially many instances of an SLINK
controller on tegra and only a single instance of SFLASH. Tegra20 is
currently ths only version of tegra that instantiates an SFLASH
controller.
This driver supports basic PIO mode of operation and is configurable
(CONFIG_OF_CONTROL) to be driven off devicetree bindings. Up to 4
devices per controller may be attached, although typically only a
single chip select line is exposed from tegra per controller so in
reality this is usually limited to 1.
To enable this driver, use CONFIG_TEGRA_SLINK

For AM335X boards, such as the EVM and Bone Linux kernel fails to
locate the device tree blob on boot. The reason being is that
u-boot is copying the DT blob to the upper part of RAM when booting
the kernel and the kernel is unable to access the blob.
By setting the fdt_high variable to 0xffffffff (to prevent the copy)
the kernel is able to locate the DT blob and boot.
This patch is tested on BeagleBone platform.

[trini: Add #define CONFIG_PHY_ADDR 0 to config]
Signed-off-by: Tom Rini <trini@ti.com>
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 OMAP4 supported boards (Panda and TI SDP4430) are used
primarily for development, this patch allows 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.

Even when the IGEPv2 board and the IGEP Computer-on-Module
are different from a form factor point of view, they are
very similar in the fact that share many components and how
they are wired.
So, it is possible (and better) to have a single board file
for both devices and just use the CONFIG_MACH_TYPE to make
a differentiation between each board when needed.
This change avoids code duplication by removing 298 lines of
code and makes future maintenance easier.
