I looked a bit closer to that now and I'm afraid to tell that running MP
on Qemu requires some extra coding work in Qemu itself. The first thing
is secondary-cpu bootup for non-linux systems which I could fix. But then
I see that cp15-c7 is completely not implemented which is required for
VA-PA translations. That's how far I looked into it for now...
