[PATCH V1 00/11] MMCONFIG refactoring and ARM64 PCI hostbridge init based on ACPI

From: Tomasz Nowicki
Date: Tue Oct 27 2015 - 12:39:27 EST


>From the functionality point of view this series might be split into two logic parts:
1. Making MMCONFIG code arch-agnostic which allows all architectures to collect
PCI config regions and used when necessary.
2. Using generic MMCONFIG code and introducing ACPI based PCI hostbridge
initialization for ARM64

Patches has been built on top of:
[Patch v7 0/7] Consolidate ACPI PCI root common code into ACPI core
https://lkml.org/lkml/2015/10/14/31
Git branch can be found here:
https://git.linaro.org/leg/acpi/acpi.git/shortlog/refs/heads/pci-acpi-upstream

This has been tested on Cavium ThunderX 1 socket server.
Any help in reviewing and testing is very appreciated.

Hanjun Guo (1):
XEN / PCI: Remove the dependence on arch x86 when PCI_MMCONFIG=y

Tomasz Nowicki (10):
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: Provide default RAW ACPI PCI config space accessors.
pci, acpi, ecam: Add flag to indicate whether ECAM region was hot
added or not.
x86, pci: Use previously added ECAM hot_added flag to remove ECAM
regions.
pci, acpi: Provide generic way to assign bus domain number.
arm64, pci, acpi: Support for ACPI based PCI hostbridge init
