Can you check out the pci/enumeration branch and see whether it accomplishes what you need? https://git.kernel.org/pub/scm/linux/kernel/git/helgaas/pci.git/log/?h=pci/enumeration > --- > arch/alpha/Kconfig | 1 + > arch/arc/Kconfig | 1 + > arch/arm/Kconfig | 1 + > arch/arm64/Kconfig | 1 + > arch/m68k/Kconfig | 1 + > arch/mips/Kconfig | 1 + > arch/sh/Kconfig | 1 + > arch/sparc/Kconfig | 1 + > arch/tile/Kconfig | 1 + > arch/unicore32/Kconfig | 1 + > drivers/pci/Kconfig | 3 +++ > drivers/pci/Makefile | 11 +---------- > 12 files changed, 14 insertions(+), 10 deletions(-) > > diff --git a/arch/alpha/Kconfig b/arch/alpha/Kconfig > index 0e49d39ea74a..30f4e711f681 100644 > --- a/arch/alpha/Kconfig > +++ b/arch/alpha/Kconfig > @@ -26,6 +26,7 @@ config ALPHA > select ODD_RT_SIGACTION > select OLD_SIGSUSPEND > select CPU_NO_EFFICIENT_FFS if !ALPHA_EV67 > + select PCI_GENERIC_SETUP > help > The Alpha is a 64-bit general-purpose processor designed and > marketed by the Digital Equipment Corporation of blessed memory, > diff --git a/arch/arc/Kconfig b/arch/arc/Kconfig > index a5459698f0ee..dd1f64858118 100644 > --- a/arch/arc/Kconfig > +++ b/arch/arc/Kconfig > @@ -44,6 +44,7 @@ config ARC > select HAVE_GENERIC_DMA_COHERENT > select HAVE_KERNEL_GZIP > select HAVE_KERNEL_LZMA > + select PCI_GENERIC_SETUP > > config MIGHT_HAVE_PCI > bool > diff --git a/arch/arm/Kconfig b/arch/arm/Kconfig > index 4c1a35f15838..86872246951c 100644 > --- a/arch/arm/Kconfig > +++ b/arch/arm/Kconfig > @@ -96,6 +96,7 @@ config ARM > select PERF_USE_VMALLOC > select RTC_LIB > select SYS_SUPPORTS_APM_EMULATION > + select PCI_GENERIC_SETUP > # Above selects are sorted alphabetically; please add new ones > # according to that.
