* alderlake: Implement chipset supportCaveh Jalali2021-02-071-44/+8
| | | | | | | | | | | | | | | | | | | | | | | This provides support for the Intel Alder Lake SoC in conjunction with the Silergy SLG4BD44540 power sequencer. A new config option (CONFIG_CHIPSET_ALDERLAKE_SLG4BD44540) is provided to enable this setup. This is intended to be used by brya and its variants. Other Alder Lake boards that use the Ice Lake style power sequencing are not affected by this new config option.
