This file is identical to stm32mp15-ddr3-1x4Gb-1066-binG.dtsi, because it is a files generated
with CubeMX with the same parameters.
Do you any reason to duplicate it ?
Do you expect some board-specific tuning or configuration with be integrated latter.
Yes, ie reason. You are right, I think will reuse exiting dtsi and update based on future requirements. I Will update in the next version, thanks!
