commit 5e866271c1b3a17af6cea1c36a482a8bdfa3b40a Author: Lin Huang hl@rock-chips.com Date: Wed Sep 21 17:05:43 2016 +0800
google/gru: set W2W_DIFFCS_DLY to 5
It will enable PHY_PER_CS_TRAINING when DDR DDR frequency >= 666. For per cs training, the controller should consider the PHY delay line switch time,there should be more cycles to switch delay line. So need increase W2W_DIFFCS_DLY_ value from 0x1 to 0x5.
BRANCH=none BUG=chrome-os-partner:56940 TEST=do memtester on kevin board, and pass
