From ebf2ed46211e0ccd82d11c34226eb578f9532a2a Mon Sep 17 00:00:00 2001 From: Aaron Durbin Date: Fri, 20 Mar 2015 10:20:15 -0500 Subject: [PATCH] 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.
