+This optional function is called by the PSCI implementation after the calling
+CPU is fully powered on with respective data caches enabled. The calling CPU and
+the associated cluster are guaranteed to be participating in coherency. This
+function gives the flexibility to perform any platform-specific actions safely,

+overhead of explicit cache maintainace operations.

+The ``target_state`` has a similar meaning as described in the ``pwr_domain_on_finish()``
+operation. The generic code expects the handler to succeed.
