0029 help
0030 The RapidIO specification describes a Output port transmit
0031 enable and a Input port receive enable. The recommended state
0032 for Input ports and Output ports should be disabled. When
0033 this switch is set the RapidIO subsystem will enable all
0034 ports for Input/Output direction to allow other traffic
0035 than Maintenance transfers.

0042 help
0043 Say Y here if you want to use DMA Engine frameork for RapidIO data
0044 transfers to/from target RIO devices. RapidIO uses NREAD and
0045 NWRITE (NWRITE_R, SWRITE) requests to transfer data between local
0046 memory and memory on remote target device. You need a DMA controller
0047 capable to perform data transfers to/from RapidIO.
