PPC to PowerPC Migration

[Andy Schmidt]

I am wondering if anyone has seen any good documentation for migrating
from the arch/ppc to arch/powerpc.  Specifically, I am working with a
Xilinx board so I am more accustom to the xparamters.h vs. device
trees.  I am very willing to build a (or multiple) tutorials to help
others in my situation, I just need some initial help getting started.
 If anyone can point me in the right direction, I will be sure to keep
the group (or those interested) updated on the documentation.

Thank you,
Andrew
