Masahiro Yamada 019167c741 kbuild: avoid build error when single DTB is turned into composite DTB ... [ Upstream commit 712aba5543b88996bc4682086471076fbf048927 ] As commit afa974b771 ("kbuild: add real-prereqs shorthand for $(filter-out FORCE,$^)") explained, $(real-prereqs) is not just a list of objects when linking a multi-object module. If a single-object module is turned into a multi-object module, $^ (and therefore $(real-prereqs) as well) contains header files recorded in the *.cmd file. Such headers must be filtered out. Now that a DTB can be built either from a single source or multiple source files, the same issue can occur. Consider the following scenario: First, foo.dtb is implemented as a single-blob device tree. The code looks something like this: [Sample Code 1] Makefile: dtb-y += foo.dtb foo.dts: #include <dt-bindings/gpio/gpio.h> /dts-v1/; / { }; When it is compiled, .foo.dtb.cmd records that foo.dtb depends on scripts/dtc/include-prefixes/dt-bindings/gpio/gpio.h. Later, foo.dtb is split into a base and an overlay. The code looks something like this: [Sample Code 2] Makefile: dtb-y += foo.dtb foo-dtbs := foo-base.dtb foo-addon.dtbo foo-base.dts: #include <dt-bindings/gpio/gpio.h> /dts-v1/; / { }; foo-addon.dtso: /dts-v1/; /plugin/; / { }; If you rebuild foo.dtb without 'make clean', you will get this error: Overlay 'scripts/dtc/include-prefixes/dt-bindings/gpio/gpio.h' is incomplete $(real-prereqs) contains not only foo-base.dtb and foo-addon.dtbo but also scripts/dtc/include-prefixes/dt-bindings/gpio/gpio.h, which is passed to scripts/dtc/fdtoverlay.
