From 13022d852d5c233894fabb62279a2ae9e0355638 Mon Sep 17 00:00:00 2001 From: Chin Liang See Date: Wed, 21 Sep 2016 10:26:03 +0800 Subject: [PATCH] arm: socfpga: de0-nano-soc: Adding handoff for SDRAM ctrlcfg.extratime1 Adding new handoff for SDRAM ctrcfg.extratime1 which is required for stable LPDDR2 operation. Since the board is using DDR3, the handoff is set to default value 0.
