I'm using a bootloader I wrote that takes advantage of the download
over USB facility of the on-die ROM.  I'm waiting for some confirmation
from TI before making the boot code available.  We have an agreement
allowing us to use their documentation under NDA to write open source
drivers but there are exclusions regarding some security features
of OMAP, etc, that I need to be sure we are in compliance with.

It shouldn't be too hard to modify u-boot to work with fsample,
but it is not something I've done.

Oops -- I missed that one.  Attached is an updated patch that includes 
board-fsample.c as well.
