commit baefacd3e2d827aa5247532a7121a933c60e7919 Author: Aaron Durbin adurbin@chromium.org Date: Tue Dec 11 17:13:17 2012 -0600
haswell: add PCI id support
In order for coreboot to assign resources properly the pci drivers need to have th proper device ids. Add the host controller and the LPC device ids for Lynx Point.
Resource assignment works correctly now w/o odd behavior because of conflicts.
