Assuming there's already a port to the architecture (e.g.
there's already a port for the CPU core, but you're doing all
new peripherals), it takes a couple weeks to do a port.  If the
basic peripherals are the same (timers, interrupt controller),
it should only take a week or so.

That assumes you already have a toolchain up and running.
