- 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
Implement initial support for MKS Robin (STM32F103ZET6) board.
Custom build script is used to generate encrypted firmware compatible with original MSK Robin bootloader (i.e. safe firmware update from SD card and possibility to go back to original close-source firmware).
