From 4e8baf9202a3de5dafeb1e26f95ded999ed5c667 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Michael=20Niew=C3=B6hner?= Date: Sun, 4 Oct 2020 14:34:41 +0200 Subject: soc/intel/*: drop useless XTAL shutdown qualification code MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The XTAL shutdown (dis)qualification bit already unconditionally gets set to 1 by FSP for these platforms, making this code redundant.
