*** Next ***
- NEW: SPIv2 driver has been implemented on: STM32F0, STM32F3, STM32F7,
STM32G0, STM32G4, STM32L4, STM32L4+.
STM32G0, STM32G4, STM32L4, STM32L4+, STM32H7.
- NEW: New SPIv2 driver model, it is compatible with the previous SPI driver
and introduces: better runtime errors handling, slave mode,
data synchronization function, various other improvements.
