ARM: introduce ARM_SINGLE_ARMV7M for ARMv7-M platforms
This introduces a new top level config symbol ARM_SINGLE_ARMV7M for non-MMU, ARMv7-M platforms. It also support multiple ARMv7-M platforms in one kernel image since the cores share the same basic memory layout and interrupt controller. However, this works only if the combined platforms also have a similar (main) memory layout. Signed-off-by: Stefan Agner <stefan@agner.ch> Signed-off-by: Arnd Bergmann <arnd@arndb.de>
