That's an odd address for a 128MB window. Can you make it 128MB aligned?
Maybe move the virtio region behind this one?
With a bit of smartness we don't need a virtio-mmio region with this
patch set anymore btw. We could just generate the virtio-mmio devices on
our platform bus on the fly.
+#define MACHVIRT_PLATFORM_HOLE (128ULL * 1024 * 1024) /* 128 MB */
As Scott mentioned in the e500 review round, "hole" is an odd name ;).
