I think with a dynamic resource there are some place above the address.  Which 
gets normally used.


Besides the mentioned file, the acpi_tables does  following:

For the acpi it takes it from resource system:

unsigned long acpi_fill_mcfg(unsigned long current)
{
         device_t dev;
         struct resource *res;

         dev = dev_find_device(PCI_VENDOR_ID_VIA, PCI_DEVICE_ID_VIA_K8M890CE_5, 0);
         if (!dev)
                 return current;

         res = find_resource(dev, K8T890_MMCONFIG_MBAR);
         if (res) {
                 current += acpi_create_mcfg_mmconfig((acpi_mcfg_mmconfig_t *)
                                 current, res->base, 0x0, 0x0, 0xff);
         }
         return current;
}
