Yes, thanks to Fabrice who did the merge.

For now, I don't use a ROM.
I only support booting Linux PREP kernels, using -kernel option.

For help, I put some infos, kernel and boot image here:
http://jocelyn.mayer.free.fr/qemu-ppc/index.htm

I'm far to emulate a real Mac, even far to emulate a real PREP:
we even don't have any kind of PCI support, which seems mandatory for
most PPC platforms...

I don't have a real boot-loader, just a few hacks that build a minimal
environment to run Linux PREP kernel without firmware support, no RTAS,
even no residual infos.
All those stuff will come later...

For now, I still have (many ?) bugs to fix in MMU and exception handling
to have a solid core emulation, then I will focus more on hardware &
firmware. My goal is to follow current MOL approach and use OpenBIOS
so qemu won't need any non-free binaries to run.
