We had originally gone ahead and implemented spin-table release method in ARMv8 u-boot
(see [1]) (the v3 of that patchset is still in works), but we have since been pointed towards
PSCI by Mark and Catalin, so we have implemented PSCI in ARMv8 u-boot and the v2 and v3
of the DTS patchset have been tested with both the spin-table and PSCI approaches.
