The current version supported in Zephyr for STM32F0 Cube is V1.9.0
STM32CubeF0
###########
Origin:
ST Microelectronics
http://www.st.com/en/embedded-software/stm32cubef0.html
Status:
version 1.9.0
Purpose:
ST Microelectronics official MCU package for STM32F0 series.
Description:
This package is an extract of official STM32CubeF0 package written by ST Microelectronics.
It is composed of STM32Cube hardware abstraction layer (HAL) and low layer (LL) plus a set
of CMSIS headers files, one for each SoC in STM32F0 series.
Dependencies:
None.

Patch List:
===========
*Current implementation of LL_SPI_TransmitData16 on F0 family
generates following warning:
"warning: dereferencing type-punned pointer will break strict-aliasing
rules [-Wstrict-aliasing]"
Besides being forbidden by rule, this cast is not needed, as register is
16 bits wide. Modification has been tested on F0 SoC.
stm32yyxx_ll_spi.h being included in soc.h file, warning is generated
at each compiled object, this commit allows a clean build.
Impacted files:
drivers/include/stm32f0xx_ll_spi.h
