2018-06-29ARM: Introduce ability to enable invalidate of BTB with ICIALLU on ↵Nishanth Menon
Cortex-A15 for CVE-2017-5715 As recommended by Arm in [1], ACTLR[0] (Enable invalidates of BTB) needs to be set[2] for BTB to be invalidated on ICIALLU. This needs to be done unconditionally for Cortex-A15 processors. Provide a config option for platforms to enable this option based on impact analysis for products. NOTE: This patch in itself is NOT the final solution, this requires: a) Implementation of v7_arch_cp15_set_acr on SoCs which may not provide direct access to ACR register. b) Operating Systems such as Linux to provide adequate workaround in the right locations. c) This workaround applies to only the boot processor. It is important to apply workaround as necessary (context-save-restore) around low power context loss OR additional processors as necessary in either firmware support OR elsewhere in OS.

Xilinx ZynqMP also contains dual Cortex R5 which can run U-Boot. This patch is adding minimal support to get U-Boot boot. U-Boot on R5 runs out of DDR with default configuration that's why DDR needs to be partitioned if there is something else running on arm64.

Currently CPU_V7 kconfig symbol supports only ARMv7A architectures under armv7 folder. This led to a misconception of creating separate folders for armv7m and armv7r. There is no reason to create separate folder for other armv7 based architectures when it can co-exist with few Kconfig symbols. As a first step towards a common folder, rename CPU_V7 as CPUV7A.

This converts the following to Kconfig: CONFIG_CONS_INDEX We have existing entries for this option in a number of places, with different guards on them. They're also sometimes used for things not directly inside of the serial driver. First, introduce a new symbol to guard the use of CONFIG_CONS_INDEX, so that in the case where we don't need this for the serial driver, but for some other use, we can still do it. Next, consolidate all of these into the single entry in drivers/serial/Kconfig. Finally, introduce CONS_INDEX_[023456] so that we can imply a correct value here to make the defconfig side of this smaller.

Move this option out of mach-omap2 Kconfig to a spot accessible by both families. We picked arch/arm/Kconfig over the TI specific board/ti/ location as this option is not specific to our boards but rather our architecture. Plus at some point this option can be changed to just SECURE_DEVICE, as having secure parts is not exclusive to TI and so other vendors can interpret this option as needed by their device configurations.
