Introduce a new LEGACY_PCI Kconfig option which gates support for legacy PCI devices including those attached to a PCI-to-PCI Express bridge and PCI Express devices using legacy I/O spaces. Note that this is different from non PCI uses of I/O ports such as by ACPI. Add dependencies on LEGACY_PCI for all PCI drivers which only target legacy PCI devices and ifdef legacy PCI specific functions in ata handling.
This effectively disables all default configurations which now depend on CONFIG_LEGACY_PCI. Yet, I don't see CONFIG_LEGACY_PCI added to configuration files which explicitly enable any of the affected configurations. Is that on purpose ? If so, I think it should at least be mentioned in the commit description. However, I think it would be more appropriate to either delete all affected configuration flags from the affected configuration files, or to add CONFIG_LEGACY_PCI=y to those files. Guenter
