Huang, Ying 7c83172b98 x86_64 EFI boot support: EFI frame buffer driver 
This patch adds Graphics Output Protocol support to the kernel.  UEFI2.0 spec
deprecates Universal Graphics Adapter (UGA) protocol and only Graphics Output
Protocol (GOP) is produced.  Therefore, the boot loader needs to query the
UEFI firmware with appropriate Output Protocol and pass the video information
to the kernel.  As a result of GOP protocol, an EFI framebuffer driver is
needed for displaying console messages.  The patch adds a EFI framebuffer
driver.  The EFI frame buffer driver in this patch is based on the Intel Mac
framebuffer driver.

The ELILO bootloader takes care of passing the video information as
appropriate for EFI firmware.

The framebuffer driver has been tested in i386 kernel and x86_64 kernel on EFI
platform.
