I was not aware that such *-u-boot.dtsi files are automatically picked for device tree compilation. > You will likely end up with > vf610-bk4-u-boot.dtsi or something to both set stdout-path > under /chosen and #include vf610-u-boot.dtsi. Why do I need to #include vf610-u-boot.dtsi in the vf610-bk4-u-boot.dtsi file as the vf610-u-boot.dtsi is picked automatically for the compilation? I guess that I shall #include vf610-bk4-u-boot.dtsi explicitly to the bk4.dts (as it is not picked up) ? > If you don't need a > board specific -u-boot.dtsi file then just vf610-u-boot.dtsi gets > picked up automatically and you're done. > Yes. Now it is clear.
