The intention of hardware spinlock is to allow two processors, that have no alternative mechanism for accomplish synchronization and mutual exclusion operations, to share resources (such as memory and/or any other element). Here, we add the hwspinlock framework, that makes possible to use those hwspinlock devices and stay platform-independent. Each platform wishing to support hardware spinlock must describe a driver using this framework. Signed-off-by: Aziz Idomar <aidomar@sequans.com>
