1Broadcom Northstar Plus SoC CPU Enable Method
2---------------------------------------------
3This binding defines the enable method used for starting secondary
4CPU in the following Broadcom SoCs:
5  BCM58522, BCM58525, BCM58535, BCM58622, BCM58623, BCM58625, BCM88312
6
7The enable method is specified by defining the following required
8properties in the corresponding secondary "cpu" device tree node:
9  - enable-method = "brcm,bcm-nsp-smp";
10  - secondary-boot-reg = <...>;
11
12The secondary-boot-reg property is a u32 value that specifies the
13physical address of the register which should hold the common
14entry point for a secondary CPU. This entry is cpu node specific
15and should be added per cpu. E.g., in case of NSP (BCM58625) which
16is a dual core CPU SoC, this entry should be added to cpu1 node.

19Example:
20	cpus {
21		#address-cells = <1>;
22		#size-cells = <0>;
23
24		cpu0: cpu@0 {
25			device_type = "cpu";
26			compatible = "arm,cortex-a9";
27			next-level-cache = <&L2>;
28			reg = <0>;
29		};
30
31		cpu1: cpu@1 {
32			device_type = "cpu";
33			compatible = "arm,cortex-a9";
34			next-level-cache = <&L2>;
35			enable-method = "brcm,bcm-nsp-smp";
36			secondary-boot-reg = <0xffff042c>;
37			reg = <1>;
38		};
39	};
