+X I2C device driver class support.

+- I-class functions for the ADC driver.

+- Evaluate making SPI and CAN drivers callback-based.

 - MAC driver for STM32F105/STM32F107 (hardware missing).

 - Device drivers for STM8 (SPI, ADC, PWM, bring it on par with STM32).

 - Support for more compilers (ARMCMx only initially).
