From 3e43749882c558875f70ac5deda39cdc9797e245 Mon Sep 17 00:00:00 2001 From: Gerd Hoffmann Date: Tue, 27 Nov 2012 08:24:42 +0100 Subject: [PATCH] acpi: drop debug port I'm pretty sure this isn't needed any more. I think this predates the switch to seabios, and the seabios DSDT table has a DBUG() aml macro which writes stuff to the seabios debug port (0x402).
