Could we not add
memory { device_type = "memory"; };
in the SoC level device trees?
This would save device_type in all other instances.
That is also how it is done in other places, e.g.
arch/arm/boot/dts/imx6qdl.dtsi
Also, could we maybe split this in two?
ARM: dts: tegra: Remove skeleton.dtsi
ARM: dts: tegra: fix DTC warnings for /memory
The first would only touch SoC level dts.
The second then would fix DTC warnings by adding the address to the
memory nodes in all board files.
