From 544878b56349a74e8cb7a0e9af899b5f7fc246fc Mon Sep 17 00:00:00 2001 From: Kyösti Mälkki Date: Fri, 9 Aug 2019 11:41:15 +0300 Subject: arch/x86: Add postcar_frame_common_mtrrs() MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit As most platforms will share the subset of enabling both low RAM WB and high ROM WP MTRRs, provide them with a single function. Add possibility for the platform to skip these if required.
