	help
	  Say y here to support the OMAP Hardware Spinlock device (firstly
	  introduced in OMAP4).

	  If unsure, say N.

	  Say y here to support the Qualcomm Hardware Mutex functionality, which
	  provides a synchronisation mechanism for the various processors on
	  the SoC.

	  If unsure, say N.

	  on the SoC.

	  It's safe to say n here if you're not interested in SIRF hardware
	  spinlock or just want a bare minimum kernel.
