Subject: [U-Boot] [PATCH 1/7] m68k: add basic set of devicetrees
Date: Thu, 20 Sep 2018 23:07:49 +0200 [thread overview]
Message-ID: <20180920210755.22381-2-angelo@sysam.it> (raw)
In-Reply-To: <20180920210755.22381-1-angelo@sysam.it>
This patch adds a basic group of devicetrees, one for each
cpu, including actually just uart and dspi devices, since
these are the drivers supporting devicetree (support added
in this patch).
