Revert "Remove sandybridge and ivybridge FSP code path"
Please don't remove chipsets and mainboards without discussion and input from the owners. Someone was asking about cougar canyon 2 just a couple of weeks ago - there's obviously still interest. This reverts commit fb50124d22014742b6990a95df87a7a828e891b6. Change-Id: Icd7dcea21fa4a7808b25bb8727020701aeebffc9 Signed-off-by: Martin Roth <martinroth@google.com> Signed-off-by: Ronald G.
