This is the last use of the tristate choice.
This choice was introduced a decade ago by commit a11650e110
("rapidio: make enumeration/discovery configurable"). Since then,
RAPIDIO_ENUM_BASIC has always been the sole member.
There was no need to have this choice block.

RapidIO configuration
config HAVE_RAPIDIO bool
menuconfig RAPIDIO tristate "RapidIO support" depends on HAVE_RAPIDIO || PCI help If you say Y here, the kernel will include drivers and infrastructure code to support RapidIO interconnect devices.
source "drivers/rapidio/devices/Kconfig"
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 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.
config RAPIDIO_ENUM_BASIC tristate "Basic Enumeration method" depends on RAPIDIO 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/driver-api/rapidio/rio_cm.rst" 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.
