dp-arm	82cb2c1ad9	Use SPDX license identifiers ... To make software license auditing simpler, use SPDX[0] license identifiers instead of duplicating the license text in every file. NOTE: Files that have been imported by FreeBSD have not been modified.

dp-arm	0498343ac0	css: Ensure PSCI system off/reset is not interrupted ... If there is a pending interrupt, it is possible for the AP to come out of the final WFI before SCP has a chance to act on it. Prevent this by disabling the GIC CPU interface before issuing a WFI. Previously, SCP would not wait on WFI before taking an action but would shut down the core or system regardless.

Soby Mathew	b12a2b493e	Introduce SCP power management abstraction ... This patch introduces an additional layer of abstraction between CSS power management hooks and the SCPI driver. A new set of APIs are introduced in order to abstract out power management operations from underlying communication mechanism with the SCP. The SCPI and the associated MHU drivers are moved into a `drivers` folder in CSS. The new SCP communication abstraction layer is added in the `drivers/scp` folder. The existing CSS power management uses the new APIs to reflect this abstraction.
