Subject: [PATCH] dtc: Allow overlays to have .dtbo extension
Date:   Wed,  6 Jan 2021 15:26:08 +0530
Message-Id: <30fd0e5f2156665c713cf191c5fea9a5548360c0.1609926856.git.viresh.kumar@linaro.org>
MIME-Version: 1.0
Content-Transfer-Encoding: 8bit
Precedence: bulk

Allow the overlays to have .dtbo extension instead of just .dtb. This
allows them to be identified easily by tools as well as humans.

Allow the dtbo outform in dtc.c for the same.
