Add PSCI support to reset and power-off the board. Because this board can be used without TF-A, supply a (mandatory) PSCI implementation.
The armv8 u-boot part already contains most bits for the implementation, it is just, that it isn't compatible with the layerscape parts. Thus, we first need to clean that up and then we can add our three little functions for the PSCI support.
Changes since v1: - mark psci_update_dt() as __weak - rebase to latest master
Michael Walle (5): armv8: include psci_update_dt() unconditionally armv8: layerscape: get rid of smc_call() armv8: psci: skip setup code if we are not EL3 armv8: psci: add ARMV8_PSCI_RELOCATE Kconfig option board: sl28: add basic PSCI implementation
