From 26a682c9441b4f7312ff9f69d22029841aa245bd Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Ky=C3=B6sti=20M=C3=A4lkki?= Date: Fri, 2 Aug 2019 06:13:22 +0300 Subject: intel/baytrail,broadwell: 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.
