From c7eae7fcb11bc7dab519fca8d8902f1fbc5c3c76 Mon Sep 17 00:00:00 2001 From: York Sun Date: Thu, 11 Sep 2014 13:32:07 -0700 Subject: board/ls1021aqds: Add DDR4 support LS1021AQDS has a variant with DDR4 slot. This patch adds a new defconfig for this variant to enable DDR4 support. RAW timing parameters are not added for DDR4. The board timing parameters are only tuned for single- rank 1600 and 1800MT/s with Micron DIMM 9ASF51272AZ-2G1A1 due to DIMM availability.
