Paul Kocialkowski ed19bdaea3 omap-common: SYS_BOOT-based fallback boot device selection for peripheral boot
OMAP devices might boot from peripheral devices, such as UART or USB.
When that happens, the U-Boot SPL tries to boot the next stage (complete U-Boot)
from that peripheral device, but in most cases, this is not a valid boot device.

This introduces a fallback option that reads the SYS_BOOT pins, that are used by
the bootrom to determine which device to boot from. It is intended for the
SYS_BOOT value to be interpreted in the memory-preferred scheme, so that the
U-Boot SPL can load the next stage from a valid location.

Practically, this options allows loading the U-Boot SPL through USB and have it
load the next stage according to the memory device selected by SYS_BOOT instead
of stalling.
