But now that we have removed those we should be able to remove this. That said, I think some of the architecture includes could also be removed. On OpenRISC we are able to get away with only having the global asm-generic/pci.h so we don't need a wrapper pci.h header at all. However, I don't have everything setup to build all of those architectures so I was being a bit conservative to remove headers. I'll see what I can do in the next version. -Stafford > > +#ifndef PCIBIOS_MIN_IO > > +#define PCIBIOS_MIN_IO 0 > > +#endif > > + > > +#ifndef PCIBIOS_MIN_MEM > > +#define PCIBIOS_MIN_MEM 0 > > +#endif > > + > > +#ifndef pcibios_assign_all_busses > > +/* For bootloaders that do not initialize the PCI bus */ > > +#define pcibios_assign_all_busses() 1 > > +#endif > > + > > +/* Enable generic resource mapping code in drivers/pci/ */ > > +#define ARCH_GENERIC_PCI_MMAP_RESOURCE > > + > > +#ifdef CONFIG_PCI_DOMAINS > > +static inline int pci_proc_domain(struct pci_bus *bus) > > +{ > > + /* always show the domain in /proc */ > > + return 1; > > +} > > +#endif /* CONFIG_PCI_DOMAINS */ > > + > > +#endif /* __ASM_GENERIC_PCI_H */ > > -- > > 2.36.1 > > > > > > _______________________________________________ > > linux-arm-kernel mailing list > > linux-arm-kernel@xxxxxxxxxxxxxxxxxxx > > http://lists.infradead.org/mailman/listinfo/linux-arm-kernel
