Subject[PATCH v2 09/12] ARM: efm32: move into multiplatform
Date
From: Arnd Bergmann <arnd@arndb.de>

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.
