Subject[PATCH v5 0/9] PCI: MMCONFIG clean up
Date
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.

v4 -> v5 changes:
- improvements for Makefile logic
- provide arch-specific checks for MCFG entry
- fix MCFG injection logic (support absence of _CBA() method)

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.
