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).
Patrick Delaunay (9): stm32mp1: ram: update mask for operating mode stm32mp1: ram: increase the delay after reset to 128 cycles stm32mp1: ram: change ddr speed to kHz ARM: dts: stm32mp1: DDR config v1.44 stm32mp1: ram: update parameter array initialization stm32mp1: ram: add support for LPDDR2/LPDDR3 stm32mp1: ram: add interactive mode for DDR configuration stm32mp1: ram: add tests in DDR interactive mode stm32mp1: ram: add tuning in DDR interactive mode
