 It looks like after STM32H7 BSP was added STM added few more members to
 the stm32h7 chip family. So code addition tracked by #3910 is now a bit
 incomplete and it would be great to grab what was grabbed in the past and
 merge again since both projects
 https://github.com/STMicroelectronics/stm32h7xx_hal_driver and
 https://github.com/STMicroelectronics/STM32CubeH7 are up to date with
 latest hardware offerings from STM.
 Anyway, when I tried to do merge myself I've found several things which
 may be considered difficult for merge:
 (1) both projects seems to switch t o Unix line endings while original bsp
 submission kept original (of that time) DOS line endings.
 (2) STM changed license note in the code itself:

 Anyway, the new code adds support for following chips:
 {{{
        bsps/arm/stm32h7/include/stm32h723xx.h
         bsps/arm/stm32h7/include/stm32h725xx.h
         bsps/arm/stm32h7/include/stm32h730xx.h
         bsps/arm/stm32h7/include/stm32h730xxq.h
         bsps/arm/stm32h7/include/stm32h733xx.h
         bsps/arm/stm32h7/include/stm32h735xx.h
         bsps/arm/stm32h7/include/stm32h745xg.h
         bsps/arm/stm32h7/include/stm32h747xg.h
 }}}
 and also for Cordic and FMAC features whatever that means.
