  <para>
        RapidIO is a high speed switched fabric interconnect with
        features aimed at the embedded market.  RapidIO provides
        support for memory-mapped I/O as well as message-based
        transactions over the switched fabric network. RapidIO has
        a standardized discovery mechanism not unlike the PCI bus
        standard that allows simple detection of devices in a
        network.
  </para>
  <para>
        This documentation is provided for developers intending
        to support RapidIO on new architectures, write new drivers,
        or to understand the subsystem internals.

        <para>
                Drivers are provided a set of calls in order
                to interface with the subsystem to gather info
                on devices, request/map memory region resources,
                and manage mailboxes/doorbells.
