From bf6b83abe06ff53033e7cd74134972de6791cf26 Mon Sep 17 00:00:00 2001 From: Martin Roth Date: Sun, 11 Oct 2015 10:37:02 +0200 Subject: 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.
