- *
- *	UART routines
- *	Bedrock/L1 "PPP-like" protocol implementation
- *	System controller "message" interface (allows multiplexing
- *		of various kinds of requests and responses with
- *		console I/O)
- *	Console interface:
- *	  "l1_cons", the glue that allows the L1 to act
- *		as the system console for the stdio libraries
- *
- * Routines making use of the system controller "message"-style interface
- * can be found in l1_command.c.
