========================================================
Secondary CPU enable-method "al,alpine-smp" binding
========================================================

This document describes the "al,alpine-smp" method for
enabling secondary CPUs. To apply to all CPUs, a single
"al,alpine-smp" enable method should be defined in the
"cpus" node.

Enable method name:	"al,alpine-smp"
Compatible machines:	"al,alpine"
Compatible CPUs:	"arm,cortex-a15"
Related properties:	(none)

Note:
This enable method requires valid nodes compatible with
"al,alpine-cpu-resume" and "al,alpine-nb-service"[1].

Example:

cpus {
	#address-cells = <1>;
	#size-cells = <0>;
	enable-method = "al,alpine-smp";

	cpu@0 {
		compatible = "arm,cortex-a15";
		device_type = "cpu";
		reg = <0>;
	};

	cpu@1 {
		compatible = "arm,cortex-a15";
		device_type = "cpu";
		reg = <1>;
	};

	cpu@2 {
		compatible = "arm,cortex-a15";
		device_type = "cpu";
		reg = <2>;
	};

	cpu@3 {
		compatible = "arm,cortex-a15";
		device_type = "cpu";
		reg = <3>;
	};
};
