commit b7393513a5a06cf757235749041921345fb5940f Author: Aaron Durbin adurbin@chromium.org Date: Sat Sep 5 10:27:12 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.
