Subject: [PATCH v2 2/3] sandbox: dts: add example for barebox, hostfile backed state
Date: Mon, 9 Sep 2019 11:31:29 +0200 [thread overview]
Message-ID: <20190909093130.30666-3-ahmad@a3f.at> (raw)
In-Reply-To: <20190909093130.30666-1-ahmad@a3f.at>
Previous commit now allows probing barebox,hostfile to be probed from
device tree. Add a barebox state node that shows how to use it. It's not
included by default, same as barebox-libftdi-example.dtsi in the same
directory.
