Now we have two identical build_mcfg functions. Consolidate them in acpi/pci.c. Signed-off-by: Wei Yang <richardw.yang@linux.intel.com> v4: * ACPI_PCI depends on both ACPI and PCI * rebase on latest master, adjust arm Kconfig v3: * adjust changelog based on Igor's suggestion Message-Id: <20190521062836.6541-2-richardw.yang@linux.intel.com> Reviewed-by: Igor Mammedov <imammedo@redhat.com> Reviewed-by: Michael S.
