14
+ * Linux EFI stub v1.0 adds the following functionality:
15
+ * - Loading initrd from the LINUX_EFI_INITRD_MEDIA_GUID device path,
16
+ * - Loading/starting the kernel from firmware that targets a different
17
+ *   machine type, via the entrypoint exposed in the .compat PE/COFF section.
18
+ *
19
+ * The recommended way of loading and starting v1.0 or later kernels is to use
20
+ * the LoadImage() and StartImage() EFI boot services, and expose the initrd
21
+ * via the LINUX_EFI_INITRD_MEDIA_GUID device path.
22
+ *
23
+ * Versions older than v1.0 support initrd loading via the image load options
24
+ * (using initrd=, limited to the volume from which the kernel itself was
25
+ * loaded), or via arch specific means (bootparams, DT, etc).
26
+ *
27
+ * On x86, LoadImage() and StartImage() can be omitted if the EFI handover
28
+ * protocol is implemented, which can be inferred from the version,
29
+ * handover_offset and xloadflags fields in the bootparams structure.
