*****************************************************************************
*** Next ***
- NEW_ Modified the RTC driver to implement the persistent storage interface
instead of files interface.
- NEW: Added a new "persistent storage" base class to HAL.
- NEW: Added support for TIM21 and TIM22 in STM32 GPT driver.
- NEW: Reinforced checks in TIM-related drivers.
