> @nickdesaulniers Can you confirm whether the kernel CI report you got was intentionally setting `armv3m`? If the build isn't setting an `mcpu` then removing the CPUs won't actually break it, though what it generates likely wouldn't run correctly.

https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/arch/arm/Makefile#n74 explicitly sets `-march=armv3m`,  when trying to build `CONFIG_CPU_32v3`. We don't yet support v4 or v4t FWIW.
