[OpenBIOS] QEMU PPC support for OpenBIOS

[Wessel, Jason]

I started porting the OpenBIOS to the PPC qemu, and I was curious of the
state of the PearPC portion of the OpenBIOS.  I thought I check and ask
if there is another branch or if someone was already working in this
area or had it working.

I would be happy to collaborate and share some patches.

Nothing really works at this point, but it is further along then having
nothing:

I get that on the serial port for PPC qemu, and now I have to work
backwards to fix it up correctly.  Serial input doesn't work quite right
and that will probably be the first hurdle.

Any pointers to active or recent projects in this area would be
appreciated.

Cheers,
Jason.
