To some extend, but the user choice information is well isolated, it's all in /chosen, so it's really only that node that needs to be modified or created from scratch by the bootloader. Thus, your bootloader can pick the right static dtb for a given bitfile, and then just use libfdt to generate the right /chosen node with other informations.
