[PATCH 0/7] GRUB: Supporting Secure Boot of xen.gz

[Ross Lagerwall]

This patch series implements support for loading and verifying a signed
xen.gz binary. This would allow the same xen.gz binary to be used for
BIOS boot, UEFI boot, and UEFI boot with Secure Boot verification.
There is an accompanying Xen patch series.

The first two patches update the multiboot2 specification with the
necessary changes.

Patches 3 through 5 implement the spec changes.
Patches 6 and 7 are a couple of small changes to allow the Secure Boot
verification to happen.
