2011-02-17	drivers: hwspinlock: add OMAP implementation	Simon Que	3	-0/+241
	Add hwspinlock support for the OMAP4 Hardware Spinlock device. The Hardware Spinlock device on OMAP4 provides hardware assistance for synchronization between the multiple processors in the system (dual Cortex-A9, dual Cortex-M3 and a C64x+ DSP).

2011-02-17	drivers: hwspinlock: add framework	Ohad Ben-Cohen	4	-0/+627
	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.
