[Xen-devel] [PATCH v2 00/23] x86: multiboot2 protocol support

[Daniel Kiper <daniel.kiper@xxxxxxxxxx>]

Hi,

I am sending, long awaited, second version of multiboot2 protocol
support for legacy BIOS and EFI platforms. It fixes all major issues
discovered until now. There are still some minor problems which should
be fixed in one way or another. I will address them in next releases.

This series, in general, is not targeted to Xen 4.6. However, there are
some fixes at the beginning of it which are worth considering, I think.

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.

ARM guys should check at least patches #9 - #18 and #20. In general
earlier mentioned patches touches common EFI code but they are not
change functionality significantly.

GRUB2 patch series will follow this patch series.

GRUB2 guys should check patches #20 and #23 but I am sending to you
all Xen related patches just in case.

If you are not interested in this patch series at all please drop me
a line and I will remove you from distribution list.

Daniel
