[PATCH V6 16/20] configs: am62x_evm_a53_defconfig: Disable semi-functional PSCI reset support
From: Jan Kiszka At this point, system shutdown is not supported by the DM firmware that TF-A calls. As we can't de-select only this feature[1], declare complete PSCI reset support as non-functional so that we don't signal incomplete support to the OS via EFI runtime services. This makes power-off under Linux work again when booting via EFI.
