[Qemu-riscv] [Qemu-devel] [PATCH v5 07/15] hw/vfio: Access MemoryRegion with MemOp

[tony.nguyen]

No-op SIZE_MEMOP macro allows us to later easily convert

memory_region_dispatch_{read|write} paramter "unsigned size" into a

size+sign+endianness encoded "MemOp op".

Being a no-op macro, this patch does not introduce any logical change.
