[U-Boot] [PATCH 0/9] stm32mp1: ram: driver update

[Patrick Delaunay]

Serie with some update on the DDR driver for stm32mp1 boards

Warning: the serie need to be apply after
1) http://patchwork.ozlabs.org/project/uboot/list/?series=89855
  => for STPMIC1 rename
2) http://patchwork.ozlabs.org/project/uboot/list/?series=91497
  => for DK1/DK2, DDR configuration

The serie also 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).
