QEMU does not need and should not allocate memory for the ROM of a passthrough PCI device. So this patch initialize the particular region like any other PCI BAR of a passthrough device. When a guest will access the ROM, Xen will take care of the IO, QEMU will not be involved in it. Xen set a limit of memory available for each guest, allocating memory for a ROM can hit this limit.
