From d6f3dd83dc7d8bb66e29c489e82d4736779d7b6f Mon Sep 17 00:00:00 2001 From: Arthur Heymans Date: Wed, 27 Dec 2017 00:12:35 +0100 Subject: nb/intel/x4x: Disable watchdog, halt TCO timer and clear timeout MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Especially on ICH7 failing to do so results in i2c block read being unusable. On ICH10 this problem doesn't manifest itself that much. This moves disabling the watchdog reboot to the northbridge code like i945 (even though it technically is southbridge stuff). TESTED on Intel DG41WV: hacking on raminit is much nicer since no need to do a hard power down for +4s are needed to clear the timeouts.
