+         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.

+         Most armv8 systems have PSCI support enabled in EL3, either through
