From 6f1426ab0fad715bccbad60e976ebf420442006c Mon Sep 17 00:00:00 2001 From: "Michael S. Tsirkin" Date: Wed, 24 Jul 2013 18:56:10 +0300 Subject: ich9: APIs for pc guest info This adds APIs that will be used to fill in acpi tables, implemented using QOM, to various ich9 components. Some information is still missing in QOM, so we fall back on lookups by type instead.
