Hi,

Is mpc870 fully supported in the powerpc arch? I know it's an old
processor but 8xx is still one of platforms in the powerpc arch. If
it's not supported, how much effort will it be to resurrect mpc870 in
the new arch considering we have substantial 8xx support?

It should work, with appropriate board support -- MPC875 and MPC885 have
been used with arch/powerpc, and MPC870 is very similar (albeit with fewer
devices).

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

You need to update the case statement arch/powerpc/boot/wrapper to 
recognize your board and select cuboot-8xx.o, as is done for adder875. 
Otherwise it defaults to looking for a file for your specific board.
