[RFC PATCH V5 0/5] ECAM quirks handling for ARM64 platforms

Show all headers | View raw

Quirk handling relies on an idea of matching MCFG OEM ID, TABLE ID and
revision (the ones from standard header of MCFG table).

Static array is used to keep quirk entries. Each entry consists of
mentioned MCFG IDs along with custom pci_ops structure and initialization call.

As an example, the last patch presents quirk handling mechanism usage for
ThunderX PEM driver.

v4 -> v5
- rebase against v4.8-rc1
- rework to exact MCFG OEM ID, TABLE ID, rev match
  - use memcmp instead of strncmp
  - no substring match
- fix typos and dmesg message

Tomasz Nowicki (5):
  PCI: Embed pci_ecam_ops in pci_config_window structure
  PCI/ACPI: Move ACPI ECAM mapping to generic MCFG driver
  PCI: Check platform specific ECAM quirks
  ARM64/PCI: Start using quirks handling for ACPI based PCI host
    controller
  PCI: thunder-pem: Support quirky configuration space access for ACPI
    based PCI host controller
