From: Arnd Bergmann <arnd@xxxxxxxx> Since the multiplatform configuration can support no-MMU kernels now, there is nothing stopping us from moving the efm32 platform in there as well. This introduces a new ARCH_MULTI_V7M CPU architecture selection option, since v7-M is incompatible with v7-A, and we can have either of the two enabled for multiplatform, but not both at the same time.
