These semaphores provide a hardware locking mechanism, +// so that when a processor is already using a resource, the second processor is not +// granted that resource. There are 32 bits of Arbitration semaphores provided in the system. +// The hardware does not enforce any resource association to these bits. It is left to the +// firmware to assign and use these bits. +// Any processor that needs to access a particular resource will request for the +// corresponding bit in the Arbitration semaphores by writing a one to that bit in the +// Arbitration Semaphore Request register (SMP_GET register). Firmware will then +// check the corresponding bit in the Semaphore Granted Status register (SMP_GNT_ST register) +// If the requesting processor has been granted the resource, then the status returned will +// be a one. +// Alternately, the processor can configure the interrupt controller to generate an +// interrupt when the resource becomes available. Refer to the arictlr_arbgnt specfile for details. +// When the processor has finished using the resource, it releases the resource by writing a one +// to the corresponding bit in the Arbitration Semaphore Put Request register +// (SMP_PUT register).
