Subject: [PATCH v6 09/12] ARM: efm32: use ARM_SINGLE_ARMV7M
Use the new config symbol ARM_SINGLE_ARMV7M which groups config
symbols used by modern ARMv7-M platforms. It also support multiple
ARMv7-M platforms in one kernel image. However, this only works if
the combined platforms share the same (main) memory layout.
