[PATCH 0/4] efi: PE header generation fix
The PE headers of the generated efi file were quite buggy. And since OVMF
perform a few consistency checks, syslinux was unable to run on it. I don't
pretend to have a thorough understanding of the PE+ headers, some bugs may
remain. :)
Celelibi (4):
efi: Fix PE header field rva_and_sizes_nr
efi: Location, size and alignment of .text section
efi: Useless relocations in PE file

Since the data directories aren't ever used, can't we just delete them
and set rva_and_sizes_nr to 0?
