Right, that would be another option. vf610 is in the same category as this
one I think, it's currently in mach-imx, and we can probably leave it there.

Unless someone is going to do the patch to consolidate the cortex-m
platforms, I'd stay with mach-vexpress here, but I don't have a strong
opinion.
