The problem with this approach is that then different architectures
need different fancy options, which makes things a hassle. With the
old guarantee of each machine providing four serial ports, you could
just do -serial 1 -serial 2 and not have to worry about it. Much
nicer.

Making FDT dynamic also sounds complicated.

Could we just do the simple patch of adding four pl011s in there?
