From aba8fb115802df289007ae9df3269d65cfd008c5 Mon Sep 17 00:00:00 2001 From: Kyösti Mälkki Date: Fri, 2 Aug 2019 06:11:28 +0300 Subject: intel/i945,gm45,pineview,x4x: 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() when it is not needed and move implementation to a suitable file already building for needed stages.
