From 209431eff8afb928d72200c79153165c7d860ca0 Mon Sep 17 00:00:00 2001 From: Praneeth Bajjuri Date: Wed, 25 Mar 2015 18:25:09 -0500 Subject: [PATCH] ARM: DRA7: Enable Cortex A15 errata 798181 ARM errata 798181 is applicable for OMAP5/DRA7 based devices. So enable the same in the build. DRA7xx is based on Cortex-A15 r2p2 revision. ARM Errata extract and workaround information is as below. On Cortex-A15 (r0p0..r3p2) the TLBI*IS/DSB operations are not adequately shooting down all use of the old entries. The ARM_ERRATA_798181 option enables the Linux kernel workaround for this erratum which sends an IPI to the CPUs that are running the same ASID as the one being invalidated.
