62	RapidIO is a high speed switched fabric interconnect with
63	features aimed at the embedded market.  RapidIO provides
64	support for memory-mapped I/O as well as message-based
65	transactions over the switched fabric network. RapidIO has
66	a standardized discovery mechanism not unlike the PCI bus
67	standard that allows simple detection of devices in a
68	network.

71  	This documentation is provided for developers intending
72	to support RapidIO on new architectures, write new drivers,
73	or to understand the subsystem internals.
