Indeed, I would first start with patches that make serial_mm_init a
sysbus wrapper. Then, with techniques similar to Peter's work, it
should be possible to extend -device and do something like
-device serial-mmio,memory.addr=0x1f000000,irq=gpio[5]
or something like that.
The only difference is whether you get the information from device tree
or command line.
