commit 548620ad4900bb0949097c4d3f4dd638db2822f4
Author: Stefan Reinauer <reinauer at chromium.org>
Date: Tue Apr 23 15:00:02 2013 -0700
Fix VGA option rom INT15 handler
The format of this function changed but was not updated in
all mainboards. This fixes all Sandybridge/Ivybridge boards.
The int15 handler no longer takes a regs structure as an
argument and instead uses global variables. The yabel interface
is now similar enough that we can drop the duplicate handler.
