commit 5efc735a63e3abd21c8e8020b71a044ba937270a
Author: Aaron Durbin 
Date:   Tue Mar 17 13:20:02 2015 -0500

bootblocks: use run_romstage()

Instead of sprinkling the cbfs calls around (as well as getting
    return values incorrect) use the common run_romstage() to perform
    the necessary work to load and run romstage.
