From f6c20681d1d1fa66212ab58b6dc1e9112fe4651d Mon Sep 17 00:00:00 2001 From: Kyösti Mälkki Date: Fri, 2 Aug 2019 06:14:50 +0300 Subject: intel/nehalem,sandybridge: Move stage_cache support function MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Let garbage-collection take care of stage_cache_external_region() if it is no needed and move implementation to a suitable file already building for needed stages. Remove aliasing CONFIG_RESERVED_SMM_SIZE as RESERVED_SMM_SIZE and (unused) aliasing of CONFIG_IED_REGION_SIZE as IED_SIZE.
