Subject: x86_64-efi-boot-support-efi-frame-buffer v3
From: "Huang, Ying" <ying.huang@xxxxxxxxx>
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.
