Add support for SPI host command backend for STM32 chips family. Unfortunately, the current SPI API can't be used to handle the host commands communication. The main issues are unknown command size sent by the host(the SPI transaction sends/receives specific number of bytes) and need to constant sending status byte(the SPI module is enabled and disabled per transaction). Thus the SPI backend includes basic SPI STM32 driver adjusted to host command specification. Signed-off-by: Dawid Niedzwiecki <dawidn@google.com> |
