   support several new devices.

 - NEW: Demo for STM32F0-Discovery board.

 - NEW: Initial support for STM32F0xx devices, added a specific ADC driver.

-  Validated EXT, PAL, Serial, SPI drivers.

+  Validated EXT, GPT, ICU, PAL, PWM, Serial, SPI drivers.

 - NEW: Added a common ancestor class to the SDC and MMC_SPI drivers. This

   allows to share code and definitions.

 - NEW: Modified the SDC driver to implement the new block devices abstract
