bootm: relocate ramdisk if CONFIG_SYS_BOOT_RAMDISK_HIGH set
In 35fc84f, bootm was refactored so plain 'bootm' and
'bootm <subcommand>' shared a common implementation.
The 'bootm ramdisk' command implementation is now part of the common
implementation but not invoke by plain 'bootm' since the original
implementation never did ramdisk relocation. Instead, ramdisk
relocation happened in image_setup_linux() which is typically called
during the OS portion of 'bootm'.
On ARM, parameters to the Linux kernel can either be passed by FDT or
ATAGS. When using FDT, image_setup_linux() is called which also triggers
ramdisk relocation. When using ATAGS, image_setup_linux() is _not_
called because it mostly does FDT setup.
Instead of calling image_setup_linux() in both FDT and ATAGS cases,
include BOOTM_STATE_RAMDISK in the requested states during a plain
'bootm' if CONFIG_SYS_BOOT_RAMDISK_HIGH is set and remove the ramdisk
relocation from image_setup_linux(). This causes ramdisk relocation to
happen on any system where CONFIG_SYS_BOOT_RAMDISK_HIGH regardless of
the OS being booted. Also remove IMAGE_ENABLE_RAMDISK_HIGH as it was
only used by the now-removed code from image_setup_linux().

Since the above patch, you have to setup the fcr register.

Commit bb5930d5c97f ("exynos: video: Convert several boards to driver

for video, but this breaks backward compatibility with the stdout env
var since now stdout is expected to be "vidconsole" instead of "lcd".
This causes display to not work when updating u-boot on these boards
if the old stdout env var is used. Since these are consumer devices,
there's no easy way to have a serial console so users may be confused
thinking that u-boot failed to boot, or in the best case will need to
update the stdout env var blindly to make the display to work again.
There's a CONFIG_VIDCONSOLE_AS_LCD config option to workaround this,
so enable it in the Chromebooks' default configuration files to allow
users to change their stdout env var before the workaround is removed.
