From: Rasmus Villemoes Date: Tue, 3 Sep 2024 21:59:36 +0000 (+0200) Subject: scripts/Makefile.lib: do not include CONFIG_DEVICE_TREE_INCLUDES in dtsi_include_list X-Git-Url: http://git.dujemihanovic.xyz/?a=commitdiff_plain;h=5f044932413694475422d4b16607dfcf9aff8781;p=u-boot.git scripts/Makefile.lib: do not include CONFIG_DEVICE_TREE_INCLUDES in dtsi_include_list The commit mentioned in Fixes broke the CONFIG_DEVICE_TREE_INCLUDES feature, with the result that any board setting any non-empty value for that fails to build. The parent of the mentioned commit refactoring a bit by introducing the dtsi_include_list variable and changing cmd_dtc to loop over that was fine. However, the .dtsi files mentioned in CONFIG_DEVICE_TREE_INCLUDES are not supposed to be generated via the build system. They are meant for e.g. including a public key for verified boot (generated with the key2dtsi script), or for injecting some stuff to the /config node (say, a bootcmd or a load-environment setting or things like that). The files can either live in-tree in a private branch or completely outside, e.g. in some Yocto metadata. But regardless, U-Boot's build system will never know anything about them, so when the mentioned commit did dtsi_include_list_deps = $(addprefix $(obj)/,$(subst $(quote),,$(dtsi_include_list))) things broke, because if CONFIG_DEVICE_TREE_INCLUDES is for example "/path/to/public_key.dtsi", this would add a dependency on $(obj)//path/to/public_key.dtsi to each $(obj)/*.dtb target, yielding make[3]: *** No rule to make target 'arch/arm/dts/imx6dl-aristainetos2c_7.dtb', needed by 'dtbs'. Stop. To fix that while preserving the introduced CONFIG_EFI_CAPSULE_ESL_FILE behaviour, disentangle CONFIG_DEVICE_TREE_INCLUDES from dtsi_include_list from which dtsi_include_list_deps is built, and instead just add the items directly to the $(foreach) loop.
