commit 269fa00a33fefb3db9fe3e4e095cbd32abbec0fe Author: Sol Boucher solb@chromium.org Date: Thu Apr 30 18:02:08 2015 -0700
haswell: Link stage_cache_external_region into ramstage, too
When CONFIG_CACHE_RELOCATED_RAMSTAGE_OUTSIDE_CBMEM is set, this function is now linked into the ramstage as well as the romstage, since the former makes calls to it in panther builds. After this commit, it's possible to build panther using the config file from the Chromium OS project[1] if you supply the appropriate Intel descriptor and ME binary blobs and manually set CONFIG_VBOOT_VERIFY_FIRMWARE=n, CONFIG_BUILD_WITH_FAKE_IFD=n, and CONFIG_HAVE_ME_BIN=y. The resulting image is at least able to load a payload, although I only tested with depthcharge, which immediately complained, "vboot handoff pointer is NULL" and gave up the ghost.
