Why not use the in kernel 8250 driver (which will drive a stamdard 16540/550/554 as well ?) To ressurect one you'll need to add kref handling, rework the termios code and maybe some other bits too. Take a look how other arm boards use struct plat_serial8250_port and the serial8250 platform driver. You should just be able to declare the structures and register the platform device.
