1======================================================== 2Secondary CPU enable-method "al,alpine-smp" binding 3======================================================== 4 5This document describes the "al,alpine-smp" method for 6enabling secondary CPUs. To apply to all CPUs, a single 7"al,alpine-smp" enable method should be defined in the 8"cpus" node. 9 10Enable method name: "al,alpine-smp" 11Compatible machines: "al,alpine" 12Compatible CPUs: "arm,cortex-a15" 13Related properties: (none) 14 15Note: 16This enable method requires valid nodes compatible with 17"al,alpine-cpu-resume" and "al,alpine-nb-service"[1]. 18 19Example: 20 21cpus { 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}; 50 51-- 52[1] arm/al,alpine.txt 53
