Subject: [PATCH 4/4] ARM: phycore-am33xx: remove extra FDT memcpy
Date: Thu, 1 May 2014 23:32:52 +0200 [thread overview]
Message-ID: <1398979972-14446-5-git-send-email-l.stach@pengutronix.de> (raw)
In-Reply-To: <1398979972-14446-1-git-send-email-l.stach@pengutronix.de>
Not needed anymore, as barebox now accepts FDTs outside
of it's visible DRAM, as long as it's a valid pointer.
Signed-off-by: Lucas Stach <l.stach@pengutronix.de>
