8978f860a6 am33xx: Drop gpio0_7_pin_mux from phytec pcm051
This mux is not currently used and appears to be a carry-over from the
am335x evm code.

3e857d041f OMAP3: igep00x0: fix a build warning on IGEP boards
commit b689cd5 OMAP3: use a single board file for IGEP devices

introduced the following build warning:

igep00x0.h:168:24: warning: backslash-newline at end of file [enabled
by default]

This patch fixes the issue.

f170899f73 AM335X: Set fdt_high for AM335X devices to enable booting with Device Tree
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.

13526f7157 Add DDR3 support for AM335x-EVM (Version 1.5A)
AM335x EVM 1.5A uses Micron MT41J512M8RH-125 SDRAM 4Gb (512Mx8) as the
DDR3 chip.

d70f54808d omap4: allow the use of a plain text env file instead boot scripts
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.

9d4f542123 OMAP3: igep00x0: add boot status GPIO LED
This patch adds an GPIO LED boot status for IGEP boards.

The GPIO LED used is the red LED0 while the Linux kernel
uses the green LED0 as the boot status.

By using different GPIO LEDs, the user can know in which
step of the boot process the board currently is.

77eea28074 OMAP3: use a single board file for IGEP devices
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.
