this looks wrong, because all inherited compiled dtbs will contain memory at 0
device node, for example (with applied 4/7 from this series):

% scripts/dtc/dtc -I dtb -O dts arch/arm/boot/dts/lpc4357-ea4357-devkit.dtb
| grep -A3 memory@

	memory at 0 {
		device_type = "memory";
		reg = <0x0 0x0>;
	};
--
	memory at 28000000 {
		device_type = "memory";
		reg = <0x28000000 0x2000000>;
	};

With best wishes,
Vladimir
