Yes, bootloader and Softdevice updates will always be updated using the dual-bank approach, eventhough you're using a single bank bootloader. The bootloader will not erase the old SoftDevice or bootloader untill the new image has been correctly received and its integrity checked. A single bank bootloader will only be singlebank for application updates, i.e. it will erase the old application to make rrom for the new appliaction.
However, keep in mind that the application will be erased when performing a SoftDevice + Bootloader update so you have to DFU in the application after the SD+BL update.
that is to say when my bootloader can update application,I can use it update bootloader and SoftDevice as well as application updates? thank you ,sir
