I think the first non-am335x_evm board pulled the code we need in board/
a bit too far in the board-specific direction.

Whacking the WDT (which could be done differently I imagine based on
your other patches), calling save_omap_boot_params and UART stuff is
common.  Figuring out which DDR and how is not.  I think we can learn
from omap-common/hwinit-common.c::s_init but need to have our own in
arch/arm/cpu/armv7/am33xx/board.c and declared __weak or wrapped with
CONFIG_AM33XX since TI814x (and TI816x) are different.  Or maybe some
more thinking share still.

Do you have time for this?  Thanks!
