This patch adds the DSDT table for Q35 (new tools/libacpi/dsdt_q35.asl file). There are not many differences with dsdt.asl (for i440) at the moment, namely: - BDF location of LPC Controller - Minor changes related to FDC detection - Addition of _OSC method to inform OSPM about PCIe features supported As we are still using 4 PCI router links and their corresponding device/register addresses are same (offset 0x60), no need to change PCI routing descriptions. Also, ACPI hotplug is still used to control passed through device hot (un)plug (as it was for i440).
