From 5ecf41cc3d69e797ec0ce77c052495d2846a4aaf Mon Sep 17 00:00:00 2001 From: York Sun Date: Tue, 25 Jun 2013 11:37:46 -0700 Subject: [PATCH] powerpc/t4240qds: Adjust DDR timing for RDIMM RDIMM has different timing. Tested RDIMM is MT18JSF1G72PDZ-1G9E1 for dual rank. Single- and quad-rank are not tested due to availability.
