arm: v7: Kconfig: Rename CPU_V7 as CPU_V7A 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. Later separate Kconfig symbols can be added for CPU_V7R and CPU_V7M and can co exist in the same folder.

sunxi: move Cortex SMPEN setting into start.S According to their TRMs, Cortex ARMv7 CPUs with SMP support require the ACTLR.SMPEN bit to be set as early as possible, before any cache or TLB maintenance operations are done. As we do those things still in start.S, we need to move the SMPEN bit setting there, too. This introduces a new ARMv7 wide symbol and code to set bit 6 in ACTLR very early in start.S, and moves sunxi boards over to use that instead of the custom code we had in our board.c file (where it was called technically too late). In practice we got away with this so far, because at this point all the other cores were still in reset, so any broadcasting would have been ignored anyway. But it is architecturally cleaner to do it early, and we move a core specific piece of code out of board.c. This also gets rid of the ARM_CORTEX_CPU_IS_UP kludge I introduced a few years back, and moves the respective logic into the new Kconfig entry. Signed-off-by: Andre Przywara <andre.przywara@arm.com>
