The question is: does your "arch/ppc/platforms/ebony.h" include
<asm/ppcboot.h> or not, i. e. does it use the U-Boot definitions at
all?

There is no ebony.h in arch/ppc/platforms...the board isn't listed there at
all, neither
is the walnut [ 405 ], but I've seen numerous people discuss the fact that
they have
the ebony board working with this (linux-2.5-ocp from bk) working.

It's arch/ppc/platforms/4xx/ebony.[ch]

And no, ebony.[ch] doesn't support u-boot. So it cannot work with u-boot if you
didn't change ebony.[ch].

You cannot just substitute boot loader without changing board support in Linux
kernel and expect it to work.

I can only suggest the same thing I told you before, get Ebony running with
standard IBM boot loader (OpenBIOS), study how Linux kernel interact with _this_
bootloader, study how u-boot differs from IBM OpenBIOS and only after having
full understanding how things work, try to port Ebony to using u-boot.
