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

+ Amount of time a discovery node waits for a host to complete
+ enumeration before giving up.

+config RAPIDIO_ENABLE_RX_TX_PORTS
+ 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.
+
+config RAPIDIO_DEBUG
+ bool "RapidIO subsystem debug messages"
+ 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.

+ default RAPIDIO_ENUM_BASIC
+ help
+ There are different enumeration and discovery mechanisms offered
+ for RapidIO subsystem. You may select single built-in method or
+ or any number of methods to be built as modules.
+ Selecting a built-in method disables use of loadable methods.
+
+ If unsure, select Basic built-in.
+
+config RAPIDIO_ENUM_BASIC
+ tristate "Basic"

+ This option includes basic RapidIO fabric enumeration and discovery
+ mechanism similar to one described in RapidIO specification Annex 1.
