Ignoring the beaglebone aspect for the moment -- might support for
8250-like serial ports via OF be a good thing for the armmp kernel to
have anyway?

On first glance the platforms using those compatibility strings which I
recognise look mainly to be armel, but I've not dug into the ones I
don't recognise yet. The only one I know I have seen with an 8250 in it
is 64-bit ARM which isn't relevant in this config.
