From d357e6283631ce8e3279ef825f677482f1056e50 Mon Sep 17 00:00:00 2001 From: Patrick Georgi Date: Mon, 24 Sep 2012 20:47:03 +0200 Subject: libpayload: CMOS access was implemented in a backward way Instead of having the highlevel functions make use of the lowlevel functions, it implemented the lowlevel stuff in terms of highlevel.
