	  Say Y here to support "spin-table" enable method for booting Linux.

	  To use this feature, you must do:
	    - Specify enable-method = "spin-table" in each CPU node in the
	      Device Tree you are using to boot the kernel
	    - Let secondary CPUs in U-Boot (in a board specific manner)
	      before the master CPU jumps to the kernel

	  U-Boot automatically does:
	    - Set "cpu-release-addr" property of each CPU node
	      (overwrites it if already exists).
	    - Reserve the code for the spin-table and the release address
	      via a /memreserve/ region in the Device Tree.

	help
	  Most armv8 systems have PSCI support enabled in EL3, either through
	  ARM Trusted Firmware or other firmware.

	  On these systems, we do not need to implement system reset manually,
	  but can instead rely on higher level firmware to deal with it.

	  Select Y here to make use of PSCI calls for system reset
