commit a7a39e52530ea4f465a0bdd76fff655f54e56774 Author: Aaron Durbin adurbin@chromium.org Date: Sat Sep 5 11:08:02 2015 -0500
verstage: use common program.ld for linking
There's no reason to have a separate verstage.ld now that there is a unified stage linking strategy. Moreover verstage support is throughout the code base as it is so bring in those link script macros into the common memlayout.h as that removes one more specific thing a board/chipset needs to do in order to turn on verstage.
