+Freescale DCFG
+
+DCFG is the device configuration unit, that provides general purpose
+configuration and status for the device. Such as setting the secondary
+core start address and release the secondary core from holdoff and startup.
+
+Required properties:
+  - compatible: Should contain a chip-specific compatible string,
+	Chip-specific strings are of the form "fsl,<chip>-dcfg",
+	The following <chip>s are known to be supported:
+	ls1012a, ls1021a, ls1043a, ls1046a, ls2080a.
+
+  - reg : should contain base address and length of DCFG memory-mapped registers
+
+Example:
+	dcfg: dcfg@1ee0000 {
+		compatible = "fsl,ls1021a-dcfg";
+		reg = <0x0 0x1ee0000 0x0 0x10000>;
+	};

+Freescale SCFG

+SCFG is the supplemental configuration unit, that provides SoC specific

+status.
