From b61e06156660579ea6e248abd2506ebdd85e7a14 Mon Sep 17 00:00:00 2001 From: York Sun Date: Tue, 25 Jun 2013 11:37:47 -0700 Subject: powerpc/mpc8xxx: Add x4 DDR device support On selected platforms, x4 DDR devices can be supported. Using x4 devices may lower the performance, but generally they are available for higher density. Tested on MT36JSF2G72PZ-1G9E1 RDIMM.
