Add new machine called pegasos2 emulating the Genesi/bPlan Pegasos II,
a PowerPC board based on the Marvell MV64361 system controller and the
VIA VT8231 integrated south bridge/superio chips. It can run Linux,
AmigaOS and a wide range of MorphOS versions. Currently a firmware ROM
image is needed to boot and only MorphOS has a video driver to produce
graphics output. Linux could work too but distros that supported this
machine don't include usual video drivers so those only run with
serial console for now.

Oh, sorry about the comment in the previous patch.

I don't think we can have this default to enabled while it requires a
non-free ROM to start.

Not having it enabled though does not help those who might want to use it as they are not people who can compile their own QEMU but rely on binaries so adding it without also enabling it is like it wasn't there at all in practice. I can attempt to make some guests boot without a ROM but since guests expect an OpenFirmware client interface, I'll need something to provide that. I'm waiting for VOF to be merged for this.
