From 24507871c3c6ae4f6b460b016da7ff434cd34149 Mon Sep 17 00:00:00 2001 From: Masahiro Yamada Date: Tue, 9 Jan 2024 21:07:34 +0900 Subject: kbuild: create a list of all built DTB files It is useful to have a list of all *.dtb and *.dtbo files generated from the current build. With this commit, 'make dtbs' creates arch/*/boot/dts/dtbs-list, which lists the dtb(o) files created in the current build. It maintains the order of the dtb-y additions in Makefiles although the order is not important for DTBs. It is a (good) side effect through the reuse of the modules.order rule. Please note this list only includes the files directly added to dtb-y. For example, consider this case: foo-dtbs := foo_base.dtb foo_overlay.dtbo dtb-y := foo.dtb In this example, the list will include foo.dtb, but not foo_base.dtb or foo_overlay.dtbo.
