This is the cut down version of the earlier series omitting unfinished
patches that I plan to rework later and rebased to Mark's qemu-macppc
branch. Compared to v7 the only change is the cast to (target_ulong)
from (uint32_t) as requested by Mark in patch 1.
FWIW the reason for suggesting the cast to target_ulong is so that the
same code works for both qemu-system-ppc and qemu-system-ppc64. For
qemu-system-ppc that should correctly drop the sign extension from
32-bit, whilst still allowing someone to load a 64-bit ELF into
qemu-system-ppc64 if requested.
IMO this is part of a bigger design problem. Not all
machines main bus is 64-bit. I did some experiments
but changing that involves a lot of work.
