This board is similar to suvd3 board. So most initialisation topics
are taken from suvd3 (UART1, Ethernet, piggy PHY, flash, ram) only the
application specific chip selects differ.

Changes for v2:
- fix checkpatch.pl errors and warnings
Changes for v3:
- rebased only
Changes for v4:
- addressed comment from Kim Phillips:
- Codingsytle changes
- removed CONFIG_SYS_SICRH define, as it not exists
on 832x
