- If you say Y here, the kernel will include drivers and
- infrastructure code to support RapidIO interconnect devices.

- bool "Enable RapidIO Input/Output Ports"
- depends on RAPIDIO
- help
- 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.

- depends on RAPIDIO
- depends on DMADEVICES
- select DMA_ENGINE
- help
- Say Y here if you want to use DMA Engine frameork for RapidIO data
- transfers to/from target RIO devices. RapidIO uses NREAD and
- 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.
- If you are unsure about this, say Y here.

- depends on RAPIDIO
- help
- Say Y here if you want the RapidIO subsystem to produce a bunch of
- debug messages to the system log. Select this if you are having a
- problem with the RapidIO subsystem and want to see more of what is
- going on.
- If you are unsure about this, say N here.
