commit 1b4d1940a7f5bd95396fea61a66528b57c67f51d Author: Aaron Durbin adurbin@chromium.org Date: Wed Dec 11 17:13:10 2013 -0800
baytrail: add more iosf access functions
There's a slew of ports required to initialize baytrail's perf and power values. Therefore, add the necessary functionality in the iosf module as well as the reg_script library.
BUG=chrome-os-partner:24345 BRANCH=None TEST=Built and booted.
