   5 This document describes the "al,alpine-smp" method for
   6 enabling secondary CPUs. To apply to all CPUs, a single
   7 "al,alpine-smp" enable method should be defined in the
   8 "cpus" node.
   9
  10 Enable method name:     "al,alpine-smp"
  11 Compatible machines:    "al,alpine"
  12 Compatible CPUs:        "arm,cortex-a15"
  13 Related properties:     (none)
  14
  15 Note:
  16 This enable method requires valid nodes compatible with
  17 "al,alpine-cpu-resume" and "al,alpine-nb-service"[1].

  19 Example:
  20
  21 cpus {
  22         #address-cells = <1>;
  23         #size-cells = <0>;
  24         enable-method = "al,alpine-smp";
  25
  26         cpu@0 {
  27                 compatible = "arm,cortex-a15";
  28                 device_type = "cpu";
  29                 reg = <0>;
  30         };
  31
  32         cpu@1 {
  33                 compatible = "arm,cortex-a15";
  34                 device_type = "cpu";
  35                 reg = <1>;
  36         };
  37
  38         cpu@2 {
  39                 compatible = "arm,cortex-a15";
  40                 device_type = "cpu";
  41                 reg = <2>;
  42         };
  43
  44         cpu@3 {
  45                 compatible = "arm,cortex-a15";
  46                 device_type = "cpu";
  47                 reg = <3>;
  48         };
  49 };
