Subject: [PATCH V7 3/6] scripts: dtc: Remove the unused fdtdump.c file
Date:   Fri, 29 Jan 2021 12:54:07 +0530
Message-Id: <7ea1a9e7fd5d75b7adfc2a4c40dde2d4ea3fddf8.1611904394.git.viresh.kumar@linaro.org>
In-Reply-To: <cover.1611904394.git.viresh.kumar@linaro.org>

Content-Transfer-Encoding: 8bit
Precedence: bulk

This was copied from external DTC repository long back and isn't used
anymore. Over that the dtc tool can be used to generate the dts source
back from the dtb. Remove the unused fdtdump.c file.
