Commit 51bc085d6454 ("PCI: Improve host drivers compile test coverage")
added configuration options to allow PCI host controller drivers to be
compile tested on all architectures.
Some host controller drivers (eg PCIE_ALTERA) config entries select
the PCI_DOMAINS config option to enable PCI domains management in
the kernel. Now that host controller drivers can be compiled on
all architectures, this triggers build regressions on arches that
do not implement the PCI_DOMAINS required API (ie pci_domain_nr()):
drivers/ata/pata_ali.c: In function 'ali_init_chipset':
drivers/ata/pata_ali.c:469:38: error:
implicit declaration of function 'pci_domain_nr';
did you mean 'pci_iomap_wc'?
The PCI_DOMAINS config option is meant to be selected by the arch
configuration since it is an arch rather a than host controller option.
Move the PCI_DOMAINS selection to the sub-arch Kconfig entries,
therefore fixing the build regression.
