The idea behind this patch is to give\nthe kernel developers full control over the EFI boot process. As\nH. Peter Anvin put it,\n\n\"The \u0027kernel carries its own stub\u0027 approach been very successful in\ndealing with BIOS, and would make a lot of sense to me for EFI as\nwell.\"\n\nThis patch introduces an EFI boot stub that allows an x86 bzImage to\nbe loaded and executed by EFI firmware. The bzImage appears to the\nfirmware as an EFI application. Luckily there are enough free bits\nwithin the bzImage header so that it can masquerade as an EFI\napplication, thereby coercing the EFI firmware into loading it and\njumping to its entry point. The beauty of this masquerading approach\nis that both BIOS and EFI boot loaders can still load and run the same\nbzImage, thereby allowing a single kernel image to work in any boot\nenvironment.\n\nThe EFI boot stub supports multiple initrds, but they must exist on\nthe same partition as the bzImage. Command-line arguments for the\nkernel can be appended after the bzImage name when run from the EFI\nshell, e.g.\n\nShell\u003e bzImage console\u003dttyS0 root\u003d/dev/sdb initrd\u003dinitrd.img\n\nv7:\n - Fix checkpatch warnings.\n\nv6:\n\n - Try to allocate initrd memory just below hdr-\u003einird_addr_max.\n\nv5:\n\n - load_options_size is UTF-16, which needs dividing by 2 to convert\n to the corresponding ASCII size.\n\nv4:\n\n - Don\u0027t read more than image-\u003eload_options_size\n\nv3:\n\n - Fix following warnings when compiling CONFIG_EFI_STUB\u003dn\n\n arch/x86/boot/tools/build.c: In function ‘main’:\n arch/x86/boot/tools/build.c:138:24: warning: unused variable ‘pe_header’\n arch/x86/boot/tools/build.c:138:15: warning: unused variable ‘file_sz’\n\n - As reported by Matthew Garrett, some Apple machines have GOPs that\n don\u0027t have hardware attached.
