Message-ID: <cover.1613127681.git.viresh.kumar@linaro.org> (raw)

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.
