[Qemu-riscv] [Qemu-devel] [PATCH v4 10/15] memory: Access MemoryRegion with MemOp semantics

[tony.nguyen]

To convert interfaces of MemoryRegion access, MEMOP_SIZE and

SIZE_MEMOP no-op stubs were introduced to change syntax while keeping

the existing semantics.

Now with interfaces converted, we fill the stubs and use MemOp

semantics.
