System memory used to boot the device in System memory boot mode.
This area is reserved for STMicroelectronics and contains the bootloader which is
used to reprogram the Flash memory through one of the following interfaces:
USART1, USART3, CAN2, USB OTG FS in Device mode (DFU: device firmware

and protected against spurious write/erase operations.
