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 64bit and 32bit 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 v3: - The VIDEO_TYPE_EFI is changed to 0x70 to group VIDEO_TYPE_ better. v2: - The include files of efifb.c is cleaned up. - Make CONFIG_FB_EFI not depend on CONFIG_EFI.
