From ad8d913f42b4dff80502456a08aac06e7fbcd0dd Mon Sep 17 00:00:00 2001 From: Duncan Laurie Date: Tue, 10 Dec 2013 07:41:33 -0800 Subject: baytrail: Basic DPTF framework MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit This is not complete yet but it compiles and doesn't cause any issues by itself. It is tied into the EC pretty closely so that is part of the same commit. Once we have more of the EC support done it will need some more work to make use of those new interfaces properly.
