commit 61bc4bb6c629f1ff2339afcf449c8340d12972cc Author: Aaron Durbin adurbin@chromium.org Date: Fri Mar 20 10:20:15 2015 -0500
payload loading: remove passing of struct payload
There's no need to keep track of struct payload within the boot state machine. It is completely contained within the payload loader module.
