From 29b921b86c233eca7427e8974be2a9c6888c4dfa Mon Sep 17 00:00:00 2001 From: Mans Rullgard Date: Fri, 27 Apr 2018 10:45:15 +0100 Subject: [PATCH] ARM: mxs: let boards override entire dram parameter table If many values differ from the defaults, overriding the full table is simpler and more space efficient than tweaking it through mxs_adjust_memory_params().
