commit 6ac35557f4be3eaba8c5bb48da90769601c88d55 Author: Aaron Durbin adurbin@chromium.org Date: Wed Apr 24 16:28:52 2013 -0500
coverage: use boot state callbacks
Utilize the static boot state callback scheduling to initialize and tear down the coverage infrastructure at the appropriate points. The coverage initialization is performed at BS_PRE_DEVICE which is the earliest point a callback can be called. The tear down occurs at the 2 exit points of ramstage: OS resume and payload boot.
