*
* This header file contains APIs for configuring and controlling the event
* counters in PL310 L2 cache controller.
* PL310 has 2 event counters which can be used to count a variety of events
* like DRHIT, DRREQ, DWHIT, DWREQ, etc. This file defines configurations,
* where value configures the event counters to count a set of events.
*
* XL2cc_EventCtrInit API can be used to select a set of events and
* XL2cc_EventCtrStart configures the event counters and starts the counters.
* XL2cc_EventCtrStop diables the event counters and returns the counter values.
