marcel	0215f8085c	Add scc(4), a driver for serial communications controllers. These ... controllers typically have multiple channels and support a number of serial communications protocols. The scc(4) driver is itself an umbrella driver that delegates the control over each channel and mode to a subordinate driver (like uart(4)). The scc(4) driver supports the Siemens SAB 82532 and the Zilog Z8530 and replaces puc(4) for these devices.	2006-03-30 18:33:22 +00:00
