Default implementation of fastboot_set_reboot_flag function that depends on "bcb" commands could be used in general case if there are no need to make any platform-specific implementation, otherwise it could be disabled via Kconfig option FASTBOOT_USE_BCB_SET_REBOOT_FLAG. Please note that FASTBOOT_USE_BCB_SET_REBOOT_FLAG is mutually exclusive with some platforms which already have their own implementation of this function.
