-Broadcom Kona Family CPU Enable Method
---------------------------------------
-This binding defines the enable method used for starting secondary
-CPUs in the following Broadcom SoCs:
-  BCM11130, BCM11140, BCM11351, BCM28145, BCM28155, BCM21664
-
-The enable method is specified by defining the following required
-properties in the "cpu" device tree node:
-  - enable-method = "brcm,bcm11351-cpu-method";
-  - 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,bcm11351-cpu-method";
-			secondary-boot-reg = <0x3500417c>;
-		};

-Broadcom Northstar Plus SoC CPU Enable Method
----------------------------------------------
-This binding defines the enable method used for starting secondary
-CPU in the following Broadcom SoCs:
-  BCM58522, BCM58525, BCM58535, BCM58622, BCM58623, BCM58625, BCM88312
-
-The enable method is specified by defining the following required
-properties in the corresponding secondary "cpu" device tree node:
-  - enable-method = "brcm,bcm-nsp-smp";
-  - secondary-boot-reg = <...>;
-
-The secondary-boot-reg property is a u32 value that specifies the
-physical address of the register which should hold the common
-entry point for a secondary CPU. This entry is cpu node specific
-and should be added per cpu. E.g., in case of NSP (BCM58625) which
-is a dual core CPU SoC, this entry should be added to cpu1 node.
-
-
-Example:
-	cpus {
-		#address-cells = <1>;
-		#size-cells = <0>;
-
-		cpu0: cpu@0 {
-			device_type = "cpu";
-			compatible = "arm,cortex-a9";

+description:
+  Broadcom Northstar Plus family of SoCs are used for switching control
+  and management applications as well as residential router/gateway
+  applications. The SoC features dual core Cortex A9 ARM CPUs, integrating
+  several peripheral interfaces including multiple Gigabit Ethernet PHYs,
+  DDR3 memory, PCIE Gen-2, USB 2.0 and USB 3.0, serial and NAND flash,
+  SATA and several other IO controllers.
