From 10a584b2875a391d1036adac18955a892e56f5e3 Mon Sep 17 00:00:00 2001 From: Hu Tao Date: Fri, 26 Apr 2013 11:24:44 +0800 Subject: pvpanic: pass configurable ioport to seabios This lets seabios patch the corresponding SSDT entry. Also add fw_cfg object to /machine/fw_cfg so we can reference it elsewhere.
