Migrating from ppc to powerpc

[Shawn Jin]

Hi,

I have a project that needs port ppc drivers to the powerpc arch. I've been
searching the mailing list for some clues on what tasks they would look like
and where should be the starting point. It's been quite a while since the
powerpc arch started so the info is huge. The searching doesn't seem to be
easy task for itself. :(

Would gurus here shed some light? One thing I know of is a device tree.
Assuming a device tree is provided, how much work would it be for driver
porting?

Thanks alot,
-Shawn.
