From e00b2de71cc234a9d043125539d503bbaf08aa26 Mon Sep 17 00:00:00 2001 From: Douglas Anderson Date: Tue, 7 Jun 2016 13:49:50 -0700 Subject: rockchip: kevin/gru: Slow memory down to 300 MHz At the higher speeds stressapptest shows memory errors. We don't want to track down random problems due to simple memory corruption, so slow memory back down to 300 MHz until someone figures out how to make it faster without sacrificing reliability.
