    Add a platform-independent hwspinlock framework.
    
    Hardware spinlock devices are needed, e.g., in order to access data
    that is shared between remote processors, that otherwise have no
    alternative mechanism to accomplish synchronization and mutual exclusion
    operations.

	tristate "Generic Hardware Spinlock framework"
	help
	  Say y here to support the generic hardware spinlock framework.
	  You only need to enable this if you have hardware spinlock module
	  on your system (usually only relevant if your system has remote slave
	  coprocessors).

	  If unsure, say N.
