I just mean that if we use a single structure this code could go away

Andrei, Valdimir: ping?

 
 If idea is accepted I will prepare grub_relocator32_efi relocator too.

[PATCH v2 3/6] i386/relocator: Add grub_relocator64_efi relocator

2015-07-20 Thread Daniel Kiper 
Add grub_relocator64_efi relocator. It will be used on EFI 64-bit platforms
when multiboot2 compatible image requests MULTIBOOT_TAG_TYPE_EFI_BS. Relocator
will set lower parts of %rax and %rbx accordingly to multiboot2 specification.
On the other hand processor mode, just before jumping into loaded image, will
be set accordingly to Unified Extensible Firmware Interface Specification,
Version 2.4 Errata B, section 2.3.4, x64 Platforms, boot services. This way
loaded image will be able to use EFI boot services without any issues.

If idea is accepted I will prepare grub_relocator32_efi relocator too.
