Unless I'm missing something there's only two UARTs brought out on the
low speed expansion connector (in addition to the one on the solder pads
which is currently supported).  We should also adjust the console
default to match whatever one of the low speed expansion connector UARTs
is being used by the bootloader.

While we're at it there was a recent talk which mentioned a fairly large
amount of functionality that's apparently already "upstream" for this
device but not included in the DT, assuming that means that driver
support is there it would be good to add the corresponding DT.
