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			`/*-`

Support for Freescale QUad Integrated Communications Controller. The QUICC engine is found on various Freescale parts including MPC85xx, and provides multiple generic time-division serial channel resources, which are in turn muxed/demuxed by the Serial Communications Controller (SCC). Along with core QUICC/SCC functionality a uart(4)-compliant device driver is provided which allows for serial ports over QUICC/SCC.
