* | x86: Add support for running option ROMs natively | Simon Glass | 2014-11-25 | -0/+281 |
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> |
