Change 33832 by marcel at marcel_nfs on 2003/06/28 23:47:05

	Initial submission of the uart(4) driver. The driver is mostly
	non-functional. At this stage it's important to play with the
	hardware abstraction and the overall setup of the framework.
	The overall structure of the uart(4) driver is:
	uart_bus_*	- bus front-ends.
	uart_dev_*	- hardware device drivers.
	uart_cpu_*	- machine dependent functions.
	uart_cons.c	- low-level console code.
	uart_core.c	- the device oriented framework.
	uart_tty.c	- high-level TTY code.
