I am also in the process of trying to get u-boot up and running
on an IBM Ebony board (PPC440GP). I am also having problems,
but not the same ones that Brian is having. First, some comments
on email to this point:

I get exactly the same result:

A problem with u-boot on the ebony, perhaps? Anyone else out there
running u-boot 0.2.0 on an ebony?

The ebony board has one AM29F040B part in U60, which gives 0.5 MBytes,
and two AM29F016D parts in U55 and U58 which give 4.0 MBytes. Both Brian
and I are working with the single AM29F040B part (as far as I know, having
followed Brian's postings). This part is the bootrom for the board, and
originally contained IBM's "openbios" bootrom monitor.
Now for my problem. U-boot appears to boot properly, given the output that
shows
up on the serial console (see above). But then the console appears to go
dead; no response to
carriage returns on the keyboard. Has anyone else run into this problem; any
advice?
Thanks.
