Hi York, This generic PSCI is controlled by CONFIG_ARMV8_PSCI, if enabled, any platform can implement their own PSCI functions under this framework, this is all similar with ARMv7's.
While PPA is controlled by CONFIG_FSL_LS_PPA, and the private PSCI inside the PPA is controlled by FSL_PPA_ARMV8_PSCI, this macro depends on and selected by CONFIG_FSL_LS_PPA. That is to say, they are using separate configs, and only one of them can be enabled at one time.
