commit 63031aa7867a8019529434bfbe7136f80d38ede1 Author: Duncan Laurie dlaurie@chromium.org Date: Wed Dec 19 09:12:31 2012 -0800
haswell: more ULT/LP support and minor tweaks
- Add ME device ID for Lynxpoint LP - Add GPU device IDs for ULT - SATA init tweaks from checking against DXE reference code - Remove the ICH7 from the SPI driver so it works on all lynxpoint without having to add more LPC device ID checks - Add function disable for audio dsp and xhci, remove PCI bridge - Add interrupt route registers for new devices (needs romstage setup)
