From d5d680cacc66ef7e3c02c81dc8f3a34eabce6dfe Mon Sep 17 00:00:00 2001 From: Tony Nguyen Date: Sat, 24 Aug 2019 04:36:52 +1000 Subject: memory: Access MemoryRegion with endianness Preparation for collapsing the two byte swaps adjust_endianness and handle_bswap into the former. Call memory_region_dispatch_{read|write} with endianness encoded into the "MemOp op" operand. This patch does not change any behaviour as memory_region_dispatch_{read|write} is yet to handle the endianness. Once it does handle endianness, callers with byte swaps can collapse them into adjust_endianness.
