What does x86 do?
I think the conclusion we came to about UARTs in general was that
boards should always create the devices, and the UART models
should cope with being passed a NULL chardev backend. (This
is like real hardware, where the 2nd UART always exists even
if you haven't plugged a cable into the 2nd serial port on the
back of the box.)
