This is from Galaxy J6:

	memory@40000000 {
		device_type = "memory";
		reg = <0x0 0x40000000 0x3d800000>;
	};

	memory@80000000 {
		device_type = "memory";
		reg = <0x0 0x80000000 0x40000000>;
	};

changes to

	memory@40000000 {
		device_type = "memory";
		reg = <0x0 0x40000000 0x3d800000>,
		      <0x0 0x80000000 0x7d800000>;
	};

I assume I have changed it correctly? `free -h` displays the full
and correct memory capacity.
