I have one question. 
>From what I can see in the new code, in this example "something"
partition won't be parsed with the fixed-partition parser. Correct?

partitions {
	compatible = "fixed-partitions";
	#address-cells = <1>;
	#size-cells = <1>;

	partition at 0 {
		label = "bootloader";
		reg = <0x0 0x100000>;
		compatible = "random-parser";

		partition at 0 {
			label = "something";
			reg = <0x0 0x100>;
		};
	};
};
