From 448e386309c20ed1d22360e06192b632af0af720 Mon Sep 17 00:00:00 2001 From: Timothy Pearson Date: Tue, 24 Nov 2015 14:12:01 -0600 Subject: drivers/pc80: Add PS/2 mouse presence detect On certain Winbond SuperIO devices, when a PS/2 mouse is not present on the auxiliary channel both channels will cease to function if the auxiliary channel is probed while the primary channel is active. Therefore, knowledge of mouse presence must be gathered by coreboot during early boot, and used to enable or disable the auxiliary PS/2 port before control is passed to the operating system. Add auxiliary channel PS/2 device presence detect, and update the Winbond W83667HG-A driver to flag the auxiliary channel as disabled if no device was detected.
