Do you really want this patch ? MCU boards are deprecated.

You are right. I agree that this series is no longer needed.

I wasn't aware that the STM32 MCU boards were deprecated.
I noticed Arnd Bergmann's series, "[PATCH 10/13] ARM: stm32: remove
stm32f4/f7/h7 MCU support", after sending the patch.

Sorry for the noise.

Thanks and regards,
Dario
