Simon Glass	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. Signed-off-by: Simon Glass <sjg@chromium.org>	11 years ago

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.
