From abca2e10feebbee8b739f5f92e9cd6e7e4c1ee35 Mon Sep 17 00:00:00 2001 From: Jason Liu Date: Fri, 9 Sep 2011 17:17:47 +0800 Subject: [PATCH] ARM: mx5/mm: move i.MX50 mm stuff into mm.c MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit i.MX50 is similar enough to i.MX51/53 to handle it in a single file. No functional change.
