From 62618c17e077b22bb12bdf754ca5bf89f2ae4dcd Mon Sep 17 00:00:00 2001 From: Santosh Shilimkar <santosh.shilimkar@ti.com> Date: Wed, 19 Jun 2013 15:52:12 -0400 Subject: ARM: OMAP5: Enable Cortex A15 errata 798181 ARM errata 798181 is applicable for OMAP5 based devices. So enable the same in the build. 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.
