From: Ville Syrjälä <ville.syrj...@linux.intel.com> We want to start tracking which infoframes are enabled, so let's replace the boolean flag with a bitmask.
We'll abstract the bitmask so that it's not platform dependent. That will allow us to examine the bitmask later in platform independent code.
