Thanks. I've seen the FAQ and verified that include/asm-ppc/u-boot.h in 
U-Boot defines exactly the same struct as arch/ppc/platforms/evb405ep.h in 
Linux. I've gone so far as to just copy the Linux struct definition into 
u-boot.h, replacing the struct there with all the #ifdef's, rebuilding and 
reprogramming U-Boot on my system. That didn't help.

I'm really stuck. I know Wolfgang says I should just read the FAQs. I 
suspect it's something more complicated than that. If anybody here actually 
has an IBM 405EP evaluation board and can boot Linux using U-Boot on that 
board, I'd really be grateful if you'd contact me. I won't waste a lot of 
your time with stupid questions, but I think just a little bit of help 
would get me over this hump.
