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).

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.

introduced in OMAP4).
