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.
If it is not the case, I think you can reuse the file used by
STMicroelectronics boards DK1/DK2
in the next patch.
#include "stm32mp15-ddr3-1x4Gb-1066-binG.dtsi"
