/**
* Flash driver interface is designed to abstract away differences between
* various MCUs used in Trezor devices.
*
* Generally, flash memory is divided into sectors. On different MCUs, sectors
* may have different sizes, and therefore, different number of sectors are used
* for a given purpose. For example, on STM32F4, the sectors are relatively
* large so we use single sector for Storage. On STM32U5, the sectors are
* smaller, so we use multiple sectors for the Storage. Storage implementation
* should not care about this, and should use flash_area_t interface to access
* the flash memory.
*
* flash_area_t represents a location in flash memory. It may be contiguous, or
* it may be composed of multiple non-contiguous subareas.
*
