From e22cc0cf137149bea3a06bb29ffe06e82d8edb84 Mon Sep 17 00:00:00 2001 From: Lokesh Vutla Date: Fri, 23 Aug 2013 17:34:17 +0530 Subject: ARM: OMAP5: Avoid writing into LDO SRAM bits Writing magic bits into LDO SRAM was suggested only for OMAP5432 ES1.0. Now these are no longer applicable. Moreover these bits should not be overwritten as they are loaded from EFUSE. So avoid writing into these registers.
