From 39245c8699c68f85a5aaa3153d954370920d09c0 Mon Sep 17 00:00:00 2001 From: Tom Rini Date: Thu, 7 Nov 2013 11:42:57 -0500 Subject: am33xx: Stop modifying certain EMIF4D registers Based on the definitive guide to EMIF configuration[1] certain registers that we have been modifying (and are documented registers) should be left in their reset values rather than modified. This has been tested on AM335x GP EVM and Beaglebone White.
