From 0db1ac47ee1e88e3d3784bcdb3a0e1ea277419cc Mon Sep 17 00:00:00 2001 From: Chin Liang See <clsee@altera.com> Date: Wed, 21 Sep 2016 10:25:57 +0800 Subject: [PATCH] arm: socfpga: 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.
