Re: [Arm-dev] [PATCH] Add Xen multiboot support to grub2 for aarch64

I'm fine with carrying this patch for a little while. At some point this will need to work with Secure Boot. For now we're not signing the shims on aarch64, so it won't impact anything currently...

Backport required patches. Disable Secure Boot for now as it conflicts with the Xen patches. Increase Epoch.

• • This adds support for the Xen boot on ARM specification for arm64.
• • Introduce xen_hypervisor, xen_linux, xen_initrd and xen_xsm
• to load different binaries for xen boot;
• Introduce xen_module to load common or custom module for xen boot.
• • This Xen boot support is a separated module for aarch64,
