For STM32 machine part:

Patches 6 & 7 applied on stm32-dt-for-v4.13

Patches 8 & 9 will not be applied:
As SDRAM used on STM32 MCUs is small, I don't want to penalize other users:
  - by increasing static kernel size
  - by enabling devices which consume dynamically lot of memory

User will be free to enable it through menuconfig.

Regards
Alex
