From b7fd84a3f46da8be3bd9246f28399d15fc9c3755 Mon Sep 17 00:00:00 2001 From: Sachin Kamat Date: Tue, 13 May 2014 07:13:44 +0900 Subject: ARM: EXYNOS: Map SYSRAM through generic DT bindings Instead of hardcoding the SYSRAM details for each SoC, pass this information through device tree (DT) and make the code SoC agnostic. Generic DT SRAM bindings are used for achieving this.
