* ddr: imx8m: Return error values from LPDDR4 trainingFrieder Schrempf2020-01-071-2/+7
| | | | | | | | | | | | | In cases when the same SPL should run on boards with i.MX8MM, that differ in DDR configuration, it is necessary to try different parameters and check if the training done by the firmware suceeds or not. Therefore we return the DDR training/initialization success to the upper layer in order to be able to retry with different settings if necessary.
