Bjorn Helgaas 00e1a5d21b PCI/VPD: Defer VPD sizing until first access ... 7bac54497c ("PCI/VPD: Determine VPD size in pci_vpd_init()") reads VPD at enumeration-time to find the size. But this is quite slow, and we don't need the size until we actually need data from VPD. Dave reported a boot slowdown of more than two minutes [1]. Defer the VPD sizing until a driver or the user (via sysfs) requests information from VPD. If devices are quirked because VPD is known not to work, don't bother even looking for the VPD capability. The VPD will not be accessible at all.
