Hi, This patchset adds a generic rule for applying overlays using fdtoverlay tool and then updates unittests to get built statically using the same. V7->V8: - Patch 1 is new. - Platforms need to use dtb-y += foo.dtb instead of overlay-y += foo.dtb. - Use multi_depend instead of .SECONDEXPANSION. - Use dtb-y for unittest instead of overlay-y. - Rename the commented dtb filess in unittest Makefile as .dtbo. - Improved Makefile code (I am learning a lot every day :) V6->V7: - Dropped the first 4 patches, already merged. - Patch 1/3 is new, suggested by Rob and slightly modified by me. - Adapt Patch 3/3 to the new rule and name the overlay dtbs as .dtbo. -- Viresh Rob Herring (1): kbuild: Add generic rule to apply fdtoverlay Viresh Kumar (3): kbuild: Simplify builds with CONFIG_OF_ALL_DTBS of: unittest: Create overlay_common.dtsi and testcases_common.dtsi of: unittest: Statically apply overlays using fdtoverlay drivers/of/unittest-data/Makefile | 50 ++++++++++ drivers/of/unittest-data/overlay_base.dts | 90 +----------------- drivers/of/unittest-data/overlay_common.dtsi | 91 +++++++++++++++++++ drivers/of/unittest-data/static_base_1.dts | 4 + drivers/of/unittest-data/static_base_2.dts | 4 + drivers/of/unittest-data/testcases.dts | 18 ++-- .../of/unittest-data/testcases_common.dtsi | 19 ++++ .../of/unittest-data/tests-interrupts.dtsi | 7 -- scripts/Makefile.lib | 29 +++++- 9 files changed, 200 insertions(+), 112 deletions(-) create mode 100644 drivers/of/unittest-data/overlay_common.dtsi create mode 100644 drivers/of/unittest-data/static_base_1.dts create mode 100644 drivers/of/unittest-data/static_base_2.dts create mode 100644 drivers/of/unittest-data/testcases_common.dtsi -- 2.25.0.rc1.19.g042ed3e048af
