  30          The RapidIO specification describes a Output port transmit
  31          enable and a Input port receive enable. The recommended state
  32          for Input ports and Output ports should be disabled. When
  33          this switch is set the RapidIO subsystem will enable all
  34          ports for Input/Output direction to allow other traffic
  35          than Maintenance transfers.

  43          Say Y here if you want to use DMA Engine frameork for RapidIO data
  44          transfers to/from target RIO devices. RapidIO uses NREAD and
  45          NWRITE (NWRITE_R, SWRITE) requests to transfer data between local
  46          memory and memory on remote target device. You need a DMA controller
  47          capable to perform data transfers to/from RapidIO.
