From 5605dc6135f6f26560ef3b0c6ebc5141c531179a Mon Sep 17 00:00:00 2001 From: York Sun Date: Wed, 18 May 2016 21:11:19 -0700 Subject: [PATCH] drivers/ddr/fsl: Fix timing_cfg_2 register Commit 34e026f9 added one extra bit to wr_lat for timing_cfg_2, but with wrong bit position. It is bit 13 in big-endian, or left shift 18 from LSB. This error hasn't had any impact because we don't have fast enough DDR4 using the extra bit so far.
