*
* @brief DFU BLE SVC in bootloader. The DFU BLE SuperVisor Calls allow an application to execute
* functions in the installed bootloader.
*
* @details This module implements handling of SuperVisor Calls in the bootloader.
* SuperVisor Calls allow for an application to execute calls into the bootloader.
* Currently, it is possible to exchange bonding information (like keys) from the
* application to a bootloader supporting DFU OTA using BLE, so the update process can be
* done through an already existing bond.
*
* @note The application must make sure that all SuperVisor Calls (SVC) are forwarded to the
* bootloader to ensure correct behavior. Forwarding of SVCs to the bootloader is
* done using the SoftDevice SVC @ref sd_softdevice_vector_table_base_set with the value
* present in @c NRF_UICR->NRFFW[0].
