Nishanth Menon dbb7caf110 ARM: mach-omap2: omap5/dra7: Enable ACTLR[0] (Enable invalidates of BTB) to facilitate CVE_2017-5715 WA in OS
Enable CVE_2017_5715 and since we have our own v7_arch_cp15_set_acr
function to setup the bits, we are able to override the settings.

Without this enabled, Linux kernel reports:
CPU0: Spectre v2: firmware did not set auxiliary control register IBE bit, system vulnerable

With this enabled, Linux kernel reports:
CPU0: Spectre v2: using ICIALLU workaround

NOTE: This by itself does not enable the workaround for CPU1 (on
OMAP5 and DRA72/AM572 SoCs) and may require additional kernel patches.

This config option is used to specify the size of the portion of the total
reserved EMIF region set aside for secure OS needs that will be protected
using hardware memory firewalls. This value must be smaller than the
TI_SECURE_EMIF_TOTAL_REGION_SIZE value.
