Hi Patrick,

The dependency for .dtb = .dts is not enough in dts Makefile, as the dts files are dts pre-proprocessed (include dtsi files, as specific *-u-boot.dtsi).
For arm architecture, the dependency is correctly managed in makefile of arch/arm/dts with .cmd files, it is needed to execute make in this directory.

Issue see on stm32mp1 board
stm32mp157c-ed1.dts is included in stm32mp157c-ev1.dts and dependency is not correctly managed (ev1 is not recompiled when ed1 is modified)
Do you still see this issue?
I do not see the problem any more because the following commit fixed it.

Could you test it on the latest git version?
