Why do you think so?
As you admitted in your comment at:
https://lists.denx.de/pipermail/u-boot/2022-April/481546.html
GPT(EFI_PARTITION) is optional under the current implementation
("EFI_LOADER should imply EFI_PARTITION" in your words).
As a matter of fact, EFI_LOADER (and efi_disk.o) can be compiled in
even without any partition table types.
If you don't agree, please drop this patch.
I don't care because it won't help reducing SPL code size anyway.
