Jon,

Can you break the patch up into a few pieces, it will be easier to 
review that way.  Here are the following pieces that make sense to me:

0. New firmware interface (fw_bdt*, Kconfig, ...)
1. board code changes (everything in arch/ppc/platforms/*)
2. driver changes (things in *_io, ide, net, serial dirs -- try to give 
a better list below)
3. System changes (files in arch/ppc/syslib and include/asm-ppc)

Let me know if you feel these are reasonable, they suck, or otherwise.

Let's handle the removal in arch/m68knommu/platform/68360/commproc.c 
outside of all of this (thus isolating ourselves to PPC).

2. DRIVER CHANGES:
