I adjusted my previous DTS for the current dtc compiler. This boots on
my pcm030.

If the uboot image for the pcm030 had a redboot compatible partition
table we wouldn't need to specify them in the device tree.

	lpb at ff000000 {
		compatible = "fsl,lpb";
		#address-cells = <2>;
		#size-cells = <1>;
		ranges = <0 0 0xff000000 0x01000000>;
		
		flash at 0 {
			compatible = "cfi-flash";
			reg = <0 0 0x01000000>;
			bank-width = <2>;
			device-width = <2>;
			#size-cells = <1>;
			#address-cells = <1>;
			partition at 0 {
				label = "ubootl";
				reg = <0x00000000 0x00040000>;
			};
			partition at 40000 {
				label = "kernel";
				reg = <0x00040000 0x001c0000>;
			};
			partition at 200000 {
				label = "jffs2";
				reg = <0x00200000 0x00D00000>;
			};
			partition at f00000 {
				label = "uboot";
				reg = <0x00f00000 0x00040000>;
			};
			partition at f40000 {
				label = "oftree";
				reg = <0x00f40000 0x00040000>;
			};
			partition at f80000 {
				label = "space";
				reg = <0x00f80000 0x00080000>;
			};
		};
	};
