| |
ACPI requires to run acpi_pci_{add|remove}_bus while new PCI bus is created. This allows to do some ACPI-specific additional configuration, like PCI hotplug slot enumeration. In order to fulfill these requirements, we implement arch-specific pcibios_{add|remove}_bus calls and call acpi_pci_{add|remove}_bus from there.
