+barebox uses the same devicetree bindings as the kernel. For
+the bindings derived from the kernel look in the kernel sources
+for reference.
+
+barebox specific bindings are documented here.

+Freescale i.MX IIM (Ic Identification Module)
+
+Required properties:
+
+- compatible: fsl,imx-iim
+- reg: physical register base and size
+
+Optional properties:
+
+- barebox,provide-mac-address: Provide MAC addresses for ethernet devices. This
+  can be multiple entries in the form <&phandle bankno fuseofs> to specify a MAC
+  address to a ethernet device.
+
+Example:
+
+iim: iim@83f98000 {
+	compatible = "fsl,imx51-iim", "fsl,imx-iim";
+	reg = <0x83f98000 0x4000>;
+	barebox,provide-mac-address = <&fec 1 9>;
+};
