Soby Mathew 31244d74b3 Save 'power_state' early in PSCI CPU_SUSPEND call ... This patch adds support to save the "power state" parameter before the affinity level specific handlers are called in a CPU_SUSPEND call. This avoids the need to pass the power_state as a parameter to the handlers and Secure Payload Dispatcher (SPD) suspend spd_pm_ops. The power_state arguments in the spd_pm_ops operations are now reserved and must not be used. The SPD can query the relevant power_state fields by using the psci_get_suspend_afflvl() & psci_get_suspend_stateid() APIs. NOTE: THIS PATCH WILL BREAK THE SPD_PM_OPS INTERFACE. HENCE THE SECURE PAYLOAD DISPATCHERS WILL NEED TO BE REWORKED TO USE THE NEW INTERFACE. Change-Id: I1293d7dc8cf29cfa6a086a009eee41bcbf2f238e		2015-01-23 15:14:36 +00:00
