[Xen-devel] [PATCH v2 0/3] arm64: Add multiboot support (via fdt) for Xen boot

[fu.wei@xxxxxxxxxx]

From: Fu Wei <fu.wei@xxxxxxxxxx>

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

  - The implementation for Xen is following  <Multiboot on ARM Specification>:
    http://wiki.xen.org/wiki/Xen_ARM_with_Virtualization_Extensions/Multiboot
    and xen/docs/misc/arm/device-tree/booting.txt in Xen source code.

  - The multiboot/module commands have existed, so we use 
    xen_hypervisor/xen_module instead.

  - This Xen boot support is built into linux module for aarch64,
    and can not be used alone.

  - Adding this functionality to the existing "linux" module is for
    reusing the existing code of devicetree.

  - Add the support of xen_hypervisor/xen_module commands in 
util/grub.d/20_linux_xen.in

  - Add the introduction of xen_hypervisor/xen_module commands in docs/grub.texi

  - The example of this support is <How to boot Xen with GRUB on AArch64 the 
Foundation FVP model>
    
https://wiki.linaro.org/LEG/Engineering/Grub2/Xen_booting_on_Foundation_FVP_model_by_GRUB

Changelog:
v2: remove the patches which have been accepted.
    according to Vladimir's suggestion, change the command manes
    and relevant code:
        multiboot-->xen_hypervisor
        module-->xen_module
    improve the option parsing support for xen_hypervisor/xen_module commands.
    add a patch for adding xen_hypervisor/xen_module support
    in util/grub.d/20_linux_xen.in.
    update docs/grub.texi patch for the new command names.
