commit 37e82118c64af554355922a4bd2b7d98043c7af9 Author: Aaron Durbin adurbin@chromium.org Date: Tue May 19 08:37:23 2015 -0500
cbfs: simplify program loading
By first removing struct cbfsf and using region_devices throughout program loading we can significantly decrease the complexity. This patch is mainly for review purposes as it can squashed into the new cbfs API patch.
