+config RAPIDIO_DISC_TIMEOUT
+ int "Discovery timeout duration (seconds)"
+ depends on RAPIDIO
+ default "30"
+ ---help---
+ 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.
+
+config RAPIDIO_DMA_ENGINE
+ bool "DMA Engine support for RapidIO"
+ depends on RAPIDIO
+ select 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.
+
+choice
+ prompt "Enumeration method"
+ depends on RAPIDIO
+ 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"
+ help
+ This option includes basic RapidIO fabric enumeration and discovery
+ mechanism similar to one described in RapidIO specification Annex 1.

+
+config RAPIDIO_CHMAN
+ tristate "RapidIO Channelized Messaging driver"
+ depends on RAPIDIO
+ help
+ This option includes RapidIO channelized messaging driver which
+ provides socket-like interface to allow sharing of single RapidIO
+ messaging mailbox between multiple user-space applications.
+ See "Documentation/rapidio/rio_cm.txt" for driver description.
+
+config RAPIDIO_MPORT_CDEV
+ tristate "RapidIO /dev mport device driver"
+ depends on RAPIDIO
+ help
+ This option includes generic RapidIO mport device driver which
+ allows to user space applications to perform RapidIO-specific
+ operations through selected RapidIO mport.
