This serie fixes the stm32mp1 ram driver: - adapt voltage for the LPDDR2 and LPDDR3 - solve tuning and BIST issues - allow to skip built-in calibration
Most of these patch are available on the latest STM32MP downstrean U-Boot: https://github.com/STMicroelectronics/u-boot
Patrick Delaunay (9): ram: stm32mp1: increase vdd2_ddr: buck2 for 32bits LPDDR ram: stm32mp1: display result for software read DQS gating ram: stm32mp1: don't display the prompt two times ram: stm32mp1: tuning: add timeout for polling BISTGSR.BDDONE ram: stm32mp1: tuning: deactivate derating during BIST test ram: stm32mp1: update BIST config for tuning ram: stm32mp1_ddr: fix self refresh disable during DQS training ram: stm32mp1: reduce delay after BIST reset for tuning ram: stm32mp1: the property st,phy-cal becomes optional
