Now, the 32-bit boot protocol has been merged, so I resend this patch set. Can this patch set and 32-bit boot protocol document patch catch up with the merge window of 2.6.24? Following sets of patches add EFI/UEFI (Unified Extensible Firmware Interface) boot support to x86_64 architecture. The patches have been tested against 2.6.24-rc1 kernel on Intel platforms with EFI1.10 and UEFI2.0 firmware. With this set of patches applied, the 64 bit and 32 bit x86 kernel can be booted on x86_64 machine with UEFI64 firmware. Because the EFI memory map is converted to E820 map in bootloader, now the only needed code for booting Linux kernel on x86_64 UEFI platform is the framebuffer driver. UEFI specification can be found here: http://www.uefi.org For booting the UEFI x86_64 enabled kernel, the machine with EFI/UEFI firmware and the support of bootloader is required. Detailed usage guide can be found in Documentation/x86_64/uefi.txt, which is added in the patch: EFI boot document v2: - The include files of efifb.c is cleaned up. - Make CONFIG_FB_EFI not depend on CONFIG_EFI.
