Are you using kernel code supplied by MontaVista (MV)? I had the same
problem;
we are using MontaVista 3.0 for the Ebony board, and I had trouble with
the interface from u-boot 0.2.0 to the MV kernel. The MV code is very
specific to the bootrom supplied by IBM; that bootrom is "custom" to each
unique Ebony board, because the 2 MAC addresses are stored at the end of the
bootrom (that's the "VPD" area). I had to modify 3 MV files to get the MAC
address passed in from u-boot to be used by the MV kernel
(kernel/arch/ppc/platforms/ebony.c,
kernel/include/asm-ppc/ibm440.h, and kernel/include/asm-ppc/ibm4xx.h). I
have attached
my patches for these files.
You have always the option to completely ignore such dfaults and  use
the  mechanisms  available  in  U-Boot,  for example just storing the
addresses in U-Boot environment variables (like  95%  of  all  boards
do).

Best regards,

Wolfgang Denk
