[Qemu-devel] [PATCH v5 5/6] hw/acpi: Consolidate build_mcfg to pci.c

2019-05-19 Thread Wei Yang 
Now we have two identical build_mcfg functions.

Consolidate them in acpi/pci.c.

v4:
  * ACPI_PCI depends on both ACPI and PCI
  * rebase on latest master, adjust arm Kconfig
v3:
  * adjust changelog based on Igor's suggestion
