/*
 * Starting from version v3.0, the major version field should be interpreted as
 * a bit mask of features supported by the kernel's EFI stub:
 * - 0x1: initrd loading from the LINUX_EFI_INITRD_MEDIA_GUID device path,
 * - 0x2: initrd loading using the initrd= command line option, where the file
 *        may be specified using device path notation, and is not required to
 *        reside on the same volume as the loaded kernel image.
 *
 * The recommended way of loading and starting v1.0 or later kernels is to use
 * the LoadImage() and StartImage() EFI boot services, and expose the initrd
 * via the LINUX_EFI_INITRD_MEDIA_GUID device path.
 *
 * Versions older than v1.0 may support initrd loading via the image load
 * options (using initrd=, limited to the volume from which the kernel itself
 * was loaded), or only via arch specific means (bootparams, DT, etc).
 *
 * The minor version field must remain 0x0.
