From 40f74205da313a36ff4e8b0668be3a8aa104a896 Mon Sep 17 00:00:00 2001 From: Tony Nguyen Date: Sat, 24 Aug 2019 04:36:43 +1000 Subject: [PATCH] hw/intc/armv7m_nic: Access MemoryRegion with MemOp MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit The memory_region_dispatch_{read|write} operand "unsigned size" is being converted into a "MemOp op". Convert interfaces by using no-op size_memop. After all interfaces are converted, size_memop will be implemented and the memory_region_dispatch_{read|write} operand "unsigned size" will be converted into a "MemOp op". As size_memop is a no-op, this patch does not change any behaviour.
