    Subject[PATCH 5/5V2] Xen vga: add the xen efi video mode support
    Date
    In order to add xen efi video support, it is required to add xen-efi's new
    video type(XEN_VGATYPE_EFI_LFB) case handler in the function xen_init_vga
    and set the video type to VIDEO_TYPE_EFI to enable efi video mode.
