Merge tag 'u-boot-stm32-20190523' of https://github.com/pchotard/u-boot
- Add various STM32MP1 fixes for serial, env, clk, board, i2c ... - Add STM32MP1 DDR driver update: These update introduce the DDR interactive mode described in: https://wiki.st.com/stm32mpu/index.php/U-Boot_SPL:_DDR_interactive_mode This mode is used by the CubeMX: DDR tuning tool. https://wiki.st.com/stm32mpu/index.php/STM32CubeMX The DDR interactive mode is NOT activated by default because it increase the SPL size and slow down the boot time (200ms wait added).
