Soby Mathew 539dcedb7d Validate power_state and entrypoint when executing PSCI calls ... This patch allows the platform to validate the power_state and entrypoint information from the normal world early on in PSCI calls so that we can return the error safely. New optional pm_ops hooks `validate_power_state` and `validate_ns_entrypoint` are introduced to do this. As a result of these changes, all the other pm_ops handlers except the PSCI_ON handler are expected to be successful. Also, the PSCI implementation will now assert if a PSCI API is invoked without the corresponding pm_ops handler being registered by the platform. NOTE : PLATFORM PORTS WILL BREAK ON MERGE OF THIS COMMIT. The pm hooks have 2 additional optional callbacks and the return type of the other hooks have changed.
