[Xen-devel] [PATCH v2 0/8] Change xen.efi build and add SHIM_LOCK verification into efi_multiboot2()

[Daniel Kiper <daniel.kiper@xxxxxxxxxx>]

Hey,

As in subject... This way we get:
  - one binary which can be loaded by the UEFI loader, Multiboot and
    Multiboot2 protocols,
  - UEFI secure boot support when Xen is loaded via Multiboot2 protocol,
  - if we wish, in the future we can drop xen/xen.gz and build
    xen.efi only,
  - crash dumps generated by the xen.efi loaded from the EFI loader
    can be analyzed by crash tool,
  - simpler code,
  - simpler build,
  - Xen build will no longer depend on ld i386pep support.

This patch series functionality does not depend on any GRUB2 changes.
So, review can commence without any obstacles. Though the GRUB2 have
to be changed to provide full verification chain. This will be
discussed in separate thread.

Daniel
