-Broadcom Kona Family CPU Enable Method
---------------------------------------
-This binding defines the enable method used for starting secondary
-CPUs in the following Broadcom SoCs:
- BCM23550
-
-The enable method is specified by defining the following required
-properties in the "cpu" device tree node:
- - enable-method = "brcm,bcm23550";
- - secondary-boot-reg = <...>;
-
-The secondary-boot-reg property is a u32 value that specifies the
-physical address of the register used to request the ROM holding pen
-code release a secondary CPU. The value written to the register is
-formed by encoding the target CPU id into the low bits of the
-physical start address it should jump to.
-
-Example:
- cpus {
- #address-cells = <1>;
- #size-cells = <0>;
-
- cpu0: cpu@0 {
- device_type = "cpu";
- compatible = "arm,cortex-a9";
- reg = <0>;
- };
-
- cpu1: cpu@1 {
- device_type = "cpu";
- compatible = "arm,cortex-a9";
- reg = <1>;
- enable-method = "brcm,bcm23550";
- secondary-boot-reg = <0x3500417c>;
- };
- };
