Why not? It shouldn't be any different from other
PowerPC cores that do it. I've done it on other
83xx boards, and in fact is quite easy if you
use the low boot vector.
All of my 83xx boards had to go back to clients,
but I'll try to find another one to test out a patch
and send it.

Considering your employer, you should know :-)

Oh come on. :-) The beauty of these processor variants
is their incredible similarity. The further beauty of the
83xx is we get the nice bus controller with the
traditional PowerPC core.
Take the time to understand both the processor
technology and the features of U-Boot. Using
the CFI driver with compliant flash (which is
nearly everything these days), the only flash
configuration variable should be the maximum
size of the local bus window you want to allocate
