Hi,
These two patches (Qemu/OpenBIOS) add support for giving OpenBIOS/
PPC
a boot device with -boot command line flag, use a UUID (print only)
and call a preloaded kernel. These are passed from Qemu to OpenBIOS
using the firmware configuration device and NVRAM.
Using the -boot switch works, but I can't boot anything yet so it's
not very well tested. UUID works, but it's not added to the device
tree. Kernel crashes after the first instruction, maybe the memory
size probe corrupts memory.

The ISA IO base depends on the architecture, so I don't think you
can use
I/O port to read the architecture from the fw cfg device.
