Maybe you're misreading me? I was saying iff a device is specifically
(not accidentally) for one target foo then it may/should be placed into
hw/foo/ directory.

We already have a hw/usb/ directory, and as long as there are no target
dependencies and sufficient files I see nothing wrong with hw/timer/ or
hw/serial/.
