[Qemu-devel] [PATCH v9 02/20] memory: Introduce size_memop

[Tony Nguyen]

The memory_region_dispatch_{read|write} operand "unsigned size" is
being converted into a "MemOp op".

Introduce no-op size_memop to aid preparatory conversion of
interfaces.

Once interfaces are converted, size_memop will be implemented to
return a MemOp from size in bytes.
