From b85a87b7d6f9f12d5c71c32741c8af731ed6be7e Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Ky=C3=B6sti=20M=C3=A4lkki?= Date: Mon, 29 Dec 2014 11:32:27 +0200 Subject: intel SMI handlers: Refactor GPI SMI/SCI routing MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Move the GPI interrupt routing selection between SMI/SCI from mainboards to southbridge. There is speculation if this is all just legacy APM stuff that could be removed with a followup.
