From 4cf1831f0854623181dc4e946f63dd53e6d207bd Mon Sep 17 00:00:00 2001 Message-Id: In-Reply-To: References: From: Blue Swirl Date: Mon, 9 Apr 2012 17:38:52 +0000 Subject: [PATCH 3/3] memory: move RAM test functions to memory Rename functions with memory_region_ prefix to avoid future clashes. Change the RAM/ROM/ROMD test functions to take MemoryRegion instead of MemoryRegionSection. Adjust callers.
