The RapidIO specification describes a Output port transmit

enable and a Input port receive enable. The recommended state
|
|
|
|
|
for Input ports and Output ports should be disabled. When

this switch is set the RapidIO subsystem will enable all

|

ports for Input/Output direction to allow other traffic
|
|
|

than Maintenance transfers.

Say Y here if you want to use DMA Engine frameork for RapidIO data

NWRITE (NWRITE_R, SWRITE) requests to transfer data between local

memory and memory on remote target device. You need a DMA controller

capable to perform data transfers to/from RapidIO.
