For some unknown reasons some boards with four 512 MiB RAM chips (= 2 GiB RAM) sometimes fail to train correctly at 800 MHz with the new DDR training algorithm. Use the EEPROM to count how many times the training failed and if the training failed more than 3 times, train at 667 MHz. Signed-off-by: Marek Behún <marek.behun@nic.cz>
