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

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

  54           Say Y here if you want the RapidIO subsystem to produce a bunch of
  55           debug messages to the system log. Select this if you are having a
  56           problem with the RapidIO subsystem and want to see more of what is

  67           for RapidIO subsystem. You may select single built-in method or
  68           or any number of methods to be built as modules.
  69           Selecting a built-in method disables use of loadable methods.
