charset="utf-8" acpi_dsdt_add_pci_osc() name is confusing as it gives the impression it appends the _OSC method but in fact it also appends the _DSM method for the host bridge. Let's split the function into two separate ones and let them return the method Aml pointer instead. This matches the way it is done on x86 (build_q35_osc_method). In a subsequent patch we will replace the gpex method by the q35 implementation that will become shared between ARM and x86. acpi_dsdt_add_host_bridge_methods is a new top helper that generates both the _OSC and _DSM methods. We take the opportunity to move SUPP and CTRL in the _osc method that use them.

Rename build_q35_osc_method() into build_pci_host_bridge_osc_method() and move it into hw/acpi/pci.c. In a subsequent patch we will use this later in place of acpi_dsdt_add_pci_osc().

In GPEX, SUPP is set to CDW2 but is not further used. CTRL is same as Local0. So let gpex code reuse build_pci_host_bridge_osc_method() and remove build_host_bridge_osc(). Also add an imply ACPI_PCI clause along with PCI_EXPRESS_GENERIC_BRIDGE to compile hw/acpi/pci.c when its dependency is resolved (ie. CONFIG_ACPI_PCI). This is requested to link qemu-system-mips64el.

Also make sure the root bus is set at the entry of acpi_pcihp_init(). The rationale of that change is to be consistent with the forecoming ARM implementation where the machine passes the root bus (steming from GPEX) to the GED device through a link property.

Let the GED device handle a new PCI hotplug event. On its occurrence it calls the \\_SB.PCI0.PCNT method with the BLCK mutex held. The GED device uses a dedicated MMIO region that will be mapped by the machine code. At this point the GED still does not support PCI device hotplug in its TYPE_HOTPLUG_HANDLER implementation. This will come in a subsequent patch.

This happens for instance with the hw/acpi/ged device. In that case it becomes difficult to predict which index a specific MMIO region corresponds to when one needs to mmio map the region. Introduce a new helper that takes the name of the region instead of its index. If the region is not found this returns -1. Otherwise it maps the corresponding index and returns this latter.

GED device has regions which exist depending on some external properties and it becomes difficult to guess the index of a region. Better refer to a region by its name.
