[Skiboot] [PATCH 0/4] PCI: Use Cached Vendor/Device/Class ID

[Gavin Shan]

For one particular PCI device, their vendor/device/class IDs are retrieved
from hardware and cached. Afterwards, we needn't read them from hardware
again to avoid unnecessary PCI config traffic, which is relatively slow.

Gavin Shan (4):
  core/pci: Use cached vendor/device IDs in quirks
  hw/phb3: Use cached vendor/device IDs in phb3_check_device_quirks()
  core/pci: Use cached vendor/device/class IDs on populating device node
  core/pci: Use macro as vendor ID register offset
