Excuse me if its going OT now. Maybe, you can point me, out of your 
embedded experience, to a better source.

no illusions, maybe it sounds like, yes. I'm just thrown into this 
project with an existing design and looking for solutions. The board 
consists of an lh7a404(arm922t-core),2x64MB SDRAM,64MB Flash DoC, 
Ethernet, USB, 2xUART and extension bus, nothing else. My preferred OS 
is, of course, Linux.

If I understood you right, U-Boot is maybe not the best choice for me, 
because there are only 2KB XIP Flash available at address 0x00000000 on 
startup.

Because of the several boot-modes, the lh7a404 offers, I'm thinking in 
the meantime about to ommit the loader completely and copy the kernel 
image directly from DoC to ram and jump there.

Regards,
