[Xen-devel] [PATCH 00/18] x86: multiboot2 protocol support

[Daniel Kiper <daniel.kiper@xxxxxxxxxx>]

Hi,

I am sending, long awaited, first version of multiboot2 protocol
support for legacy BIOS and EFI platforms.

The final goal is xen.efi binary file which could be loaded by EFI
loader, multiboot (v1) protocol (only on legacy BIOS platforms) and
multiboot2 protocol. This way we will have:
  - smaller Xen code base,
  - one code base for xen.gz and xen.efi,
  - one build method for xen.gz and xen.efi;
    xen.efi will be extracted from xen file
    using objcopy; PE header will be contained
    in ELF file and will precede Xen code,
  - xen.efi build will not so strongly depend
    on a given GCC and binutils version.

GRUB2 patch series will follow this patch series.

GRUB2 guys should check patch #18 but I am sending
to you all Xen related patches just in case.

Daniel
