From edc1ba7a7a13b1c721f2a7791ff809633d85fb9b Mon Sep 17 00:00:00 2001 From: Fam Zheng Date: Mon, 5 May 2014 15:53:41 +0800 Subject: [PATCH] docs/memory.txt: Fix document on MMIO operations .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).
