I would really prefer not to see any more standalone machine types,
but rather have ARMv7-M as one of the options for the
multiplatform configuration. In particular, that would let us
do *build* testing on a combined mxcm4/efm32/vexpress kernel,
although that kernel would clearly not be usable anywhere
because of the restrictions of nommu machines.

Can you make vf610_mscm_init get called from irqchip and remove this
function?
