So far on H7, the HAL used is older code base which is clearly BSD-3 
license:

https://git.rtems.org/rtems/tree/bsps/arm/stm32h7/hal/stm32h7xx_hal.c#n22

however to support new boards or peripherals I've imported few files 
which use the same unclear license message. I've clarified it in any 
imported file like:

https://git.rtems.org/rtems/tree/bsps/arm/stm32h7/boards/stm/stm32h757i-eval/system_stm32h7xx.c#n35

the problem is obviously scalability of this solution and future merges. 
You can do that one one/two board files, but probably not on whole HAL 
with ~100 files.
I also remember that Sebastian recommended to completely replace this 
license note with the specified license (to which note points). But I've 
not done that due to reluctancy of touching STM license notes here and 
hence came with committer clarification message below every such note.

Hence I asked Duc on discord to ask here for advice. BTW, new HAL for H7 
will be probably in the same situation like Duc seing with current F4.

So we definitely need to find a solution to this issue.

Thanks,
