This series is against tip:efi/core.

Patches 1-9 are small cleanups and refactoring of the code in
libstub/gop.c.

The rest of the patches add the ability to use a command-line option to
switch the gop's display mode.

The options supported are:
video=efifb:mode=n
	Choose a specific mode number
video=efifb:<xres>x<yres>[-(rgb|bgr|<bpp>)]
	Specify mode by resolution and optionally color depth
video=efifb:auto
	Let the EFI stub choose the highest resolution mode available.

The mode-setting additions increase code size of gop.o by about 3k on
x86-64 with EFI_MIXED enabled.

Arvind Sankar (14):
  efi/gop: Remove redundant current_fb_base
  efi/gop: Move check for framebuffer before con_out
  efi/gop: Get mode information outside the loop
  efi/gop: Factor out locating the gop into a function
  efi/gop: Slightly re-arrange logic of find_gop
  efi/gop: Move variable declarations into loop block
  efi/gop: Use helper macros for populating lfb_base
  efi/gop: Use helper macros for find_bits
  efi/gop: Remove unreachable code from setup_pixel_info
  efi/gop: Add prototypes for query_mode and set_mode
  efi/gop: Allow specifying mode number on command line
  efi/gop: Allow specifying mode by <xres>x<yres>
  efi/gop: Allow specifying depth as well as resolution
  efi/gop: Allow automatically choosing the best mode
