commit 11c2d69b36d58e98af04abfbd089d3300d77302c Author: Aaron Durbin adurbin@chromium.org Date: Tue Mar 17 11:43:44 2015 -0500
loaders: add program_loading.h header file
Instead of two headers for payload and ramstage loading combine the 2 files into one. This also allows for easier refactoring by keeping header files consistent.
