From 62e4d357aae0c7438c537bdb1c86909d7cac2663 Mon Sep 17 00:00:00 2001 From: Rob Herring Date: Fri, 21 Dec 2012 22:42:40 +0100 Subject: ARM: 7609/1: disable errata work-arounds which access secure registers In order to support secure and non-secure platforms in multi-platform kernels, errata work-arounds that access secure only registers need to be disabled. Make all the errata options that fit in this category depend on !CONFIG_ARCH_MULTIPLATFORM. This will effectively remove the errata options as platforms are converted over to multi-platform.
