From 1aa3d08a0244506b94031522e54fe06ee7a5ae0e Mon Sep 17 00:00:00 2001 From: Dave Liu Date: Wed, 16 Dec 2009 10:24:38 -0600 Subject: fsl-ddr: add override for the Rtt_Wr Different boards may require different settings of Dynamic ODT (Rtt_Wr). We provide a means to allow the board specific code to provide its own value of Rtt_Wr.
