	help
	  Alder Lake SoC based OEM board design with UFS and non-UFS planned to use an
	  unified AP firmware which demanded to have a unified descriptor. It means UFS
	  controller needs to default fuse enabled to let UFS SKU to boot.

	  On such design with non-UFS SKU is exhibiting S0ix failure due to UFS remain
	  enabled in the strap although FSP-S is making the UFS controller function
	  disabled. The potential root cause of this behaviour is although the UFS
	  controller is function disabled but MPHY clock is still in active state.

	  A possible solution to this problem is to issue a warm reboot (if boot path is
	  S5->S0 or G3->S0) after disabling the UFS and let PMC to read the function
	  disable state of the UFS for disabling the MPHY clock.

	  Mainboard users with such board design where OEM would like to use an unified AP
	  firmware to support both UFS and non-UFS sku booting might need to choose this
	  config to allow disabling UFS while booting on the non-UFS SKU.
	  Note: selection of this config would introduce an additional warm reset in
	  cold-reset scenarios due to function disabling of the UFS controller.
