I've seen other use cases, e.g. the extension of the du node's "clocks" and "clock-names" properties from arch/arm64/boot/dts/renesas/r8a7795.dtsi to arch/arm64/boot/dts/renesas/r8a7795-salvator-x.dts. To avoid the proliferation of "-append" versions of existing properties, what about handling this in dtc, by adding support for an "/append-property/" keyword? bootargs = "first part" ... /append-property/ bootargs = " second part".
