Enable OF_UPSTREAM to use upstream DT and add marvell/ prefix to the DEFAULT_DEVICE_TREE for Kirkwood boards. And so we can directly build DTBs from dts/upstream/src/arm/marvell, and including *-u-boot.dtsi files from arch/arm/dts/ directory. Background: The following 2 commands and filters were used in the analysis to determine which upstream DTS and DTSI files can be used as they are, or need to have modified/created *-u-boot.dtsi for u-boot specific implementation, and which board should be opt-out from OF_UPSTREAM. "git grep -li arch_kirkwood configs | xargs grep DEVICE_TREE | cut -d '"' -f2 | xargs -n1 sh -c 'diff -qs arch/arm/dts/$1.dts dts/upstream/src/arm/marvell/$1.dts' sh | grep differ" "diff -qrbu arch/arm/dts/ dts/upstream/src/arm/marvell/ | grep kirkwood | grep ".dtsi "" More detailed information can be found at: https://lore.kernel.org/u-boot/20240328021825.17935-1-mibodhi@gmail.com/T/#u I've regression tested this patch with the Zyxel NSA325 (Kirkwood 88F6282) and Zyxel NSA310S (Kirkwood 88F6281). The Zyxel NSA325 board has a USB 3.0 controller attached to the PCIe bus. And the Zyxel NSA310S has an extensive overhaul in bindings and styles in upstream DTS version.
