So anything related to stm32mp1 should have > stm32mp1_* filename prefix, and then some vendor_ or board_ suffix. Agree it is better and more coherent. I wasn't want to change the dh files, but I will do it: configs/stm32mp1_common.h or stm32mp15_common.h configs/stm32mp1_dh_dhsom.h (as you proposed) or stm32mp15_dh_dhsom.h configs/stm32mp1_st_stm32mp15.h or stm32mp15_st_common.h or stm32mp15_st_boards.h (name to be confirmed) with - stm32mp1_* filename prefix for STM32MP1 Series (Cortex arm v7) - stm32mp15_* filename prefix for STM32MP15x lines - stm32mp13_* filename prefix for STM32MP13x lines (coming soon => https://lwn.net/Articles/864174/) Regards Patrick
