Currently we use memory_region_init_rom_nomigrate() to create the "io" memory region to pass to pci_register_root_bus(). This is a dummy region, because this PCI controller doesn't support accesses to PCI IO space. There is no reason for the dummy region to be a RAM region; it is only used as a place where PCI BARs can be mapped, and if you could get a PCI card to do a bus master access to the IO space it should not get acts-like-RAM behaviour. Use a simple container memory region instead. (We do have one PCI card model which can do bus master accesses to IO space -- the LSI53C895A SCSI adaptor.) This avoids the oddity of having a memory region which is RAM but where the RAM is not migrated. Note that the size of the region we use here has no effect on behaviour.
