Author: wmb Date: Mon Sep 20 21:34:18 2010 New Revision: 1957 URL: http://tracker.coreboot.org/trac/openfirmware/changeset/1957
Log: OLPC trac 10371 - Fixed regression caused by svn 1841, which had the unintended side effect of preventing the XO-1.5 HDAudio CODEC's vendor-specific registers from being configured correctly. That in turn prevented the thermal protection from being turned on, in addition to numerous other incorrect settings like amplifier power.
