In theory, this should have no effect on the NXP reference boards as they are all blacklisted from CONFIG_PSCI_RESET in arch/arm/cpu/armv8/Kconfig. Regards, Mathew

This allows the use of PSCI calls to trusted firmware to initiate reset and poweroff events with CONFIG_PSCI_RESET and CONFIG_ARM_PSCI_FW. This is desirable, for example, if the target board has implemented a custom reset or poweroff procedure in EL3.
