Hi @rahmanih ,

I suggest to

1. add stm32_drivers under fx_drivers folder which regroup other semi-vendor delivred fx drivers

 common
    |_ fx_drivers
       |_ stm32
       |_ nxp...
       |_ ............ 

2. add a readme file to guide users who start from this files, what to modify to avoid compilation error. (for example #include "stm32XXXX.h" --> #include "stm32h7xx.h")

With regards MAy

Thank you @rahmanih - this looks good!

I will need to hold off on merging it for the moment as we are still finalizing the new development process. We need to make sure all new contributions are compliant with that process, so we can continue to obtains safety certification for this code base.
