Subject: [PATCH v2 1/2] mips: mscc: build FIT image for Ocelot
Date: Tue, 26 Jun 2018 13:57:11 +0200 [thread overview]
Message-ID: <20180626115712.11643-1-alexandre.belloni@bootlin.com> (raw)
Ocelot now has a u-boot port, allow building FIT images instead of relying
on the legacy detection and builtin DTB.
