[Qemu-devel] [PATCH] docs/memory.txt: Fix document on MMIO operations


From: Fam Zheng
Subject: [Qemu-devel] [PATCH] docs/memory.txt: Fix document on MMIO operations
Date: Mon, 5 May 2014 15:53:41 +0800

.impl.valid should be .impl.unaligned and the description needs some
fixes.

.old_portio is removed since commit b40acf99b (ioport: Switch
dispatching to memory core layer).
