This change will cause duplicated memory node entries in the DT as
noted by Vladimir Zapolskiy [1]. Same goes for all the other patch
where you make this change.
$ scripts/dtc/dtc -I dtb -O dts arch/arm/boot/dts/s3c2416-smdk2416.dtb
| grep -A2 memory
memory {
device_type = "memory";
reg = <0x0 0x0>;
};
--
memory@30000000 {
reg = <0x30000000 0x4000000>;
};
