From d19ee5c27ec0c144bae294b4317e03738616a593 Mon Sep 17 00:00:00 2001 From: Simon Glass Date: Thu, 1 Jan 2015 16:18:02 -0700 Subject: x86: ivybridge: Only run the Video BIOS when video is enabled This takes about about 700ms on link when running natively and 900ms when running using the emulator. It is a waste of time if video is not enabled, so don't bother running the video BIOS in that case. We could add a command to run the video BIOS later when needed, but this is not considered at present.
