+* ARM Snoop Control Unit(SCU)
+
+ARM cores often have a configurable SCU to the memory system through
+the AXI interfaces.
+
+Required properties:
+
+- compatible : "arm,cortex-a9-scu"
+- reg : Specifies base physical address and size of the SCU registers.
+
+Example:
+	scu {
+		compatible = "arm,cortex-a9-scu";
+		reg = <0x50040000 0x58>;
+	};
