From dec327b03b2fbf6dc6f89599107f645ed6a5396f Mon Sep 17 00:00:00 2001 From: Simon Yang Date: Fri, 22 Apr 2022 14:07:16 +0800 Subject: soc/intel/jasperlake: Revert CdClock setting Revert CdClock setting and use default value 0xff. Previous problem was fixed by Jasperlake FSP in version 1.3.09.31, so we can use the original CdClock setting in baseboard.
