It isn't tied to MIPS at all. All Adrian seems to be doing is making what was automatic configuration a little more manual. Well, strictly speaking yes. But what I'll do later is make a 'uart_core' and then allow my MIPS platforms to only register the uart(s) they need. Right now it includes all of the uarts in sys/dev/uart/. They're not separate devices. Adrian
