Hello, Here is an attempt to make some changes in the kernel to allow building of device tree overlays. While at it, I would also like to discuss about how we should mention the base DT blobs in the Makefiles for the overlays, so they can be build tested to make sure the overlays apply properly. A simple way is to mention that with -base extension, like this: $(overlay-file)-base := platform-base.dtb Any other preference ? Also fdtoverlay is an external entity right now, and is not part of the kernel. Do we need to make it part of the kernel ? Or keep using the external entity ? Thanks. -- Viresh Viresh Kumar (2): kbuild: Add support to build overlays (%.dtbo) scripts: dtc: Handle outform dtbo Makefile | 4 ++-- scripts/Makefile.lib | 12 ++++++++++++ scripts/dtc/dtc.c | 2 ++ 3 files changed, 16 insertions(+), 2 deletions(-) -- 2.25.0.rc1.19.g042ed3e048af
