f4a6f0aed0 x86: Tidy up VESA mode numbers
There are some bits which should be ignored when displaying the mode number.
Make sure that they are not included in the mode that is displayed.

818f602112 x86: Use cache, don't clear the display in video BIOS
There is no need to run with the cache disabled, and there is no point in
clearing the display frame buffer since U-Boot does it later.

e6126a5872 x86: move arch-specific asmlinkage to <asm/linkage.h>
Commit 65dd74a674 (x86: ivybridge: Implement SDRAM init) introduced
x86-specific asmlinkage into arch/x86/include/asm/config.h.

Commit ed0a2fbf14 (x86: Add a definition of asmlinkage) added the
same macro define again, this time, into include/common.h.
(Please do not add arch-specific stuff to include/common.h any more;
it is already too cluttered.)

The generic asmlinkage is defined in <linux/linkage.h>.  If you want
to override it with an arch-specific one, the best way is to add it
to <asm/linkage.h> like Linux Kernel.

0ca2426bea x86: Add support for running option ROMs natively
On x86 machines we can use an emulator to run option ROMS as with other
architectures. But with some additional effort (mostly due to the 16-bit
nature of option ROMs) we can run them natively. Add support for this.
