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.
