[U-Boot] [PATCH v4 0/6] Add ARMv8 PSCI framework

[Hongbo Zhang]

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.
