Add functionality for loading firmware files provided by the vendor to be flashed into the device's internal flash memory. The firmware consists of several components, such as the firmware executable itself, chip-specific customizations, and configuration files. The firmware file contains at least a flash utility, which is executed on the device side, and one or more flashable components. Each component has its own specific properties, such as the address where it should be loaded during flashing, one or more destination flash pages, and the flashing method that should be used.
