+ * @brief Device Firmware Update module type and function declaration for init packet handling.
+ *
+ * @details This header contains basic functionality for performing safety checks on software
+ * updates for \nRFXX based devices. It provides a skeleton for pre-checking an init packet
+ * to ensure the following image is compatible with this device. A safety check should
+ * always be performed to prevent accidental flashing of unsupported applications or a
+ * wrong combination of application and SoftDevice.
+ * The device information contains information such as:
+ * - Device type (2 bytes), for example Heart Rate. The device type is a number defined by
+ * the customer. It can be located in UICR or FICR.
+ * - Device revision (2 bytes), for example major revision 1, minor revision 0. The device
+ * revision is a number defined by the customer. It can be located in UICR or FICR.
+ * - List of SoftDevices supported by this application, for example
+ * 0x0049 = S110v6_0_0
+ * 0xFFFE = S110 development (any SoftDevice accepted),
+ * - CRC or hash of firmware image
+ *
+ * @note This module does not support security features such as image signing, but the corresponding
+ * implementation allows for such extensions.
+ * If the init packet is signed by a trusted source, it must be decrypted before it can be
+ * processed.
