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.
