You can make the BeagleBone boot via EFI, but it requires a hybrid partition table (ROM loader want DOS, EFI needs GPT). A Debian integration with this can be found for Isar [1] in this series [2]. It's only using upstream sources (plus still one u-boot patch to get wifi working). If you want legacy script booting, I suspect you need to flip some extra switches explicitly by now.
