ARM: remove support for NOMMU ARMv4/v5

2022-03-17T08:13:13Z

It is possible to build MMU-less kernels for Cortex-M base microcrontrollers as well as a couple of older platforms that have not been converted to CONFIG_ARCH_MULTIPLATFORM, specifically ep93xx, footbridge, dove, sa1100 and s3c24xx. It seems unlikely that anybody has tested those configurations in recent years, as even building them is frequently broken. A patch I submitted caused another build time regression in this configuration. I sent a patch for that, but it seems better to also remove the option entirely, leaving ARMv7-M as the only supported Arm NOMMU target for simplicity. A couple of platforms have dependencies on CONFIG_MMU, those can all be removed now. Notably, mach-integrator tries to support MMU-less CPU cores, but those have not actually been selectable for a long time. This addresses several build failures in randconfig builds that have accumulated over the years.

ARM: mach-bcm: disable ftrace in SMC invocation routines

2022-02-10T08:54:54Z

The SMC calling convention uses R7 as an argument register, which conflicts with its use as a frame pointer when building in Thumb2 mode. Given that Clang with ftrace does not permit frame pointers to be disabled, let's omit this compilation unit from ftrace instrumentation. Signed-off-by: Ard Biesheuvel Acked-by: Nick Desaulniers

ARM: bcm: Removed forced select of interrupt controllers

Now that the various second level interrupt controllers have been moved to IRQCHIP_PLATFORM_DRIVER and they do default to ARCH_BRCMSTB and ARCH_BCM2835 where relevant, remove their forced selection from the machine entry to allow an user to build them as modules.
