From de26ef99bddbce4ed225f93afcf0bee99c3b6f87 Mon Sep 17 00:00:00 2001 From: Wolfgang Denk Date: Sat, 16 May 2009 10:47:38 +0200 Subject: [PATCH] mpc512x: Move common files to share them by several boards We will soon see several new MPC521x based boards added. This patch moves files that are not board specific to a common directory so they can be shared by all such ports. It also splits off common IDE code into a new file, cpu/mpc512x/ide.c .
