MarlinFirmware/Marlin/src/HAL/HAL_STM32F1/watchdog_STM32F1.cpp
Tanguy Pruvot 287df7a61f STM32F1: various small changes
- init the led pin as output (like other HALs)
- reduce sdio dma priority to normal.. highest is never the best...
- allow fsmc only on compatible STM32F1 (like HAL fsmc)
- fsmc: remove an useless C style cast
