- FIX: Fixed SYSCFG clock not started in STM32L1/F4 HALs (bug 3449139).
- FIX: Fixed wrong definitions in STM32L-Discovery board file (bug 3449076).
- OPT: Improved the exception exit code in the GCC Cortex-Mx ports.
- NEW: Added a Time Measurement driver to the HAL, this generic driver uses
the realtime counters abstracted in the HAL driver.
