+ help
+ Enable support for power domain control in SPL. Many SoCs allow
+ power to be applied to or removed from portions of the SoC (power
+ domains). This may be used to save power. This API provides the
+ means to control such power management hardware. This enables
+ the drivers in drivers/power/domain as part of a SPL build.
