  61   <para>
  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.
