I think this utility is quite useful also for other projects.

Currently both grub and U-Boot try to compile binaries without
relocations and use objcopy to create EFI binaries. But in some aspects
these do not comply to PE standard. And having to compile without
relocations poses a lot of challenges.

Future developments of elf2efi could include support for more relocation
types. This would allow building with way less restrictions.

Another direction of thought would be trying to bring the missing
functionality for EFI building that you provide with elf2efi into binutils.

Best regards
