From 81653478ebcce72de0daac725f5756872133cfbc Mon Sep 17 00:00:00 2001 From: Stefan Agner <stefan.agner@toradex.com> Date: Tue, 4 Dec 2018 11:10:21 +0100 Subject: [PATCH] ARM: vf610: ddrmc: do not write CR79 by default The current value CTLUPD_AREF(0) is the reset value of the register, so there is no need to write a value. If needed, the register can be written using board specific CR settings.
