Would a short term fix be to create a multi-stage boot, similar to what
x86 does?  Put a small bootloader on a u-boot supported partition of
some sort that's only job is to load /boot from a UFS filesystem, and
then that bootloader loads the kernel.  This would also be compatible
with older boards/firmware.

Apologies if this is already what ARM boards do.  I've only ever
netbooted ARM boards from u-boot.

Cheers,
Simon.
