ppc-softmmu/qemu-system-ppc -M prep

My current theory is that bios_addr and bios_size are insufficient for
the MemoryRegion - binary ppc_rom.bin is 524.3 KB only and may be trying
to relocate parts of itself to the exception vectors, so we may need to
use a fixed size of 1 MB and location 0xfff00000 for the MemoryRegion.
Checking...
