[U-Boot] [PATCH v2 00/13] ARMv7: add PSCI support to u-boot
PSCI is an ARM standard that provides a generic interface that supervisory software can use to manage power in the following situations: - Core idle management - CPU hotplug - big.LITTLE migration models - System shutdown and reset It basically allows the kernel to offload these tasks to the firmware, and rely on common kernel side code.
