Thanks Scott. I found your implementation in the kernel. I use
adder875 as my base to port my board support. But I'm having a problem
in the last step to create the cuImage. You may know what I did wrong.
The error message is as follows.

  WRAP    arch/powerpc/boot/cuImage.my870
ppc_8xx-ld: arch/powerpc/boot/cuboot-my870.o: No such file: No such
file or directory
make[1]: *** [arch/powerpc/boot/cuImage.my870] Error 1

I believe the default cuboot-8xx.c should be enough for my board to
fix up the board settings. I don't know why the linker was looking for
this cuboot-my870.o object file.

BTW, my kernel is 2.6.33.5.

Thanks,
-Shawn.
