Subject: [PATCH V5 4/5] kbuild: Add support to build overlays (%.dtbo)
Date: Wed, 20 Jan 2021 12:36:46 +0530 [thread overview]
Message-ID: <6e57e9c84429416c628f1f4235c42a5809747c4c.1611124778.git.viresh.kumar@linaro.org> (raw)
In-Reply-To: <cover.1611124778.git.viresh.kumar@linaro.org>
Add support for building DT overlays (%.dtbo). The overlay's source file
will have the usual extension, i.e. .dts, though the blob will have
.dtbo extension to distinguish it from normal blobs.
