[Xen-devel] [PATCH v3 0/4] arm64: Add Xen boot support (via fdt)

[fu.wei@xxxxxxxxxx]

From: Fu Wei <fu.wei@xxxxxxxxxx>

  - This adds support for the Xen boot on ARM specification for arm64.

  - Add and export some accessor functions of "loaded" flag and
    grub_linux_get_fdt function in include/grub/arm64/linux.h for xen boot.

  - 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,
    but reuse the existing code of devicetree in linux module.

  - Add the support of xen_hypervisor, xen_linux and xen_initrd
    in util/grub.d/20_linux_xen.in

  - Add the introduction of all xen boot commands in docs/grub.texi

  - The example of this support is <How to boot Xen with GRUB on AArch64 the 
Foundation FVP model>
