From 90870d9846e6a302823712acf6d40f947e60ed75 Mon Sep 17 00:00:00 2001 From: york Date: Fri, 2 Jul 2010 22:25:59 +0000 Subject: [PATCH] powerpc/8xxx: Fix quad-rank DIMMs support on corenet_ds board. The board specific parameters associated with quad rank dimms where missing. This fixes it so the board will function if quad rank dimms are placed in it.
