New Revision: 335226
URL: https://svnweb.freebsd.org/changeset/base/335226

Log:
  Check for a 'pci' prefix rather than a full match in get_addr_props
  
  Summary:
  Newer OPAL device trees, such as those on POWER9 systems, use 'pciex' for
  device_type, not 'pci'.  Rather than enumerating all possible variants, just
  check for a 'pci' prefix.
