Hi Bjorn,

Any comments before I post next version ?

Regards,
Tomasz

MCFG ACPI table and PCI ECAM standard have no arch dependencies so it can be
used across all architectures. Currently MMCONFIG related code resides in
arch/x86 directories. This patch set is going to isolate non-architecture
specific code and make it accessible for all architectures.

v3 -> v4 changes:
- bug fixes after kbuild test robot report
     - add asm/io.h header for ecam.c
     - rename mmcfg -> ecam for drivers/xen/pci.c and arch/x86/pci/numachip.c
- rework Kconfig logic

v2 -> v3 changes:
- rebase patch set v2 to v4.0-rc1

v1 -> v2 changes:
- use generic readb/readw etc. accessors instead of AMD Fam10h workaround
- separate ACPI and ECAM code
- improve ECAM code naming

Tomasz Nowicki (9):
   x86, pci: Clean up comment about buggy MMIO config space access for
     AMD Fam10h CPUs.
   x86, pci: Abstract PCI config accessors and use AMD Fam10h workaround
     exclusively.
   x86, pci: Reorder logic of pci_mmconfig_insert() function
   x86, pci, acpi: Move arch-agnostic MMCONFIG (aka ECAM) and ACPI code
     out of arch/x86/ directory
   pci, acpi, mcfg: Provide generic implementation of MCFG code
     initialization.
   x86, pci: mmconfig_{32,64}.c code refactoring - remove code
     duplication.
   x86, pci, ecam: mmconfig_64.c becomes default implementation for ECAM
     driver.
   pci, acpi, mcfg: Share ACPI PCI config space accessors.
   pci, ecam: Improve naming for ecam.c content and areas where it is
     used.
