From 10ae1cf2cda38e681849dcc9e6e86ee3330a8b17 Mon Sep 17 00:00:00 2001 From: Michael Niewöhner Date: Sun, 11 Oct 2020 14:05:32 +0200 Subject: {cpu,soc}/intel: deduplicate cpu code MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Move a whole bunch of copy-pasta code from soc/intel/{bdw,skl,cnl,icl, tgl,ehl,jsl,adl} and cpu/intel/{hsw,model_*} to cpu/intel/common. This change just moves the code. Rework is done in CB:46588.
