You could make the PL011 user instantiate-able and make the necessary
changes to use the dynamic FDT node generation framework (sysbus-fdt),
and then you'd be able to add as many additional UARTs as you like to
mach-virt's platform bus. I played around with that idea once, and have
some patches rotting somewhere that could maybe be dug back up.
