  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.
