Hello neither the helloworld.efi of qemu-x86_64_defconfig nor the u-boot-payload.efi of efi-x86_payload64_defconfig can be started from the firmware of my Thinkpad 585 while grubx64.efi works fine.
Looking at the generated PE header I found the following abnormality: coff.PointerToSymbolTable != 0 coff.NumberOfSymbols != 0 (using https://github.com/xypron/efi_analyzer) According to the Microsoft Portable Executable and Common Object File Format Specification - rev 11 - 2017-01-17 these fields should be 0. The U-Boot executables have these sections which do not exist in grubx64.efi, the EFI shell, and the Windows loader: Section[3] .dynamic Section[4] .dynsym So I think we have to change something in the linking to get usable EFI binaries.
