menuconfig SSB
	tristate "Sonics Silicon Backplane support"

	help
	  Support for the Sonics Silicon Backplane bus.
	  You only need to enable this option, if you are
	  configuring a kernel for an embedded system with
	  this bus.
	  It will be auto-selected if needed in other
	  environments.

	  The module will be called ssb.

	  If unsure, say N.
