+Subject: [PATCH 3/3] arm: mvebu: turris_omnia: Reset the board immediately on
+ DDR training failure
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+The state of the current DDR training code for Armada 38x is such that
+we cannot be sure it will always train successfully - although after the
+last change we were yet unable to find a board that failed DDR training,
+from experience in the last 2 years we know that it is possible.
+
+The experience also tells us that in many cases the board fails training
+only sometimes, and after a reset the training is successful.
+
+Enable the new option that makes the board reset itself on DDR training
+failure immediately. Until now we called hang() in such a case, which
+meant that the board was reset by the MCU after 120 seconds.
