37 // Description: Simple driver for the SH Serial Communication Interface
38 // The driver can be used for either the SCIF or the IRDA
39 // modules (the latter can act as the former).
40 // Clients of this file can configure the behavior with:
41 // CYGNUM_SCIF_PORTS: number of SCI ports
42 //
43 // Note: It should be possible to configure a channel to IRDA mode.
44 // Worry about that when some board needs it.
