Better to just not depend on the DTB at all for basic operation. ie. don't brick the board if the DTB is unavailable.
Is it even possible to have a "recovery mode U-Boot" that is not tied to the specific board it's built for? Either U-Boot is reliable, or it's generic (i.e. uses the DTB for configuration). I just don't see how it can be both.
A recovery U-boot would only need to be generic enough to provide a console and means to upload and run code through that console. If that works well, then you have a reliable and (as) generic (as it gets) recovery u-boot (granted, it would still depend on the console working out-of-the-boot without any HW tricks like enabling voltage converters and such).
