Hi, I have made a custom board with stm32mp135f
and I tried to boot using yocto for stm32mp135f-dk and got an error in the tf-a part(fsbl) because i do not have a pmic in my board,
every change that i am doing for the dts file i get an error when i "bitbake tf-a-stm32mp",
each time is a different error.
Can someone help me with how to change the dts file for it to work?

If your board does not have the STPMIC, you can simply remove all mention of it from the DTS. Compare with the DTS from my custom board: https://github.com/js216/stm32mp135_test_board/blob/main/config/custom.dts 

You can try to adapt the code the my repository to fit your board.

Alternatively, can you post what errors you get?
