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.
