New Revision: 346408
URL: https://svnweb.freebsd.org/changeset/base/346408

Log:
  Add UEFI definitions related to converting string to DEVICE_PATH
  
  Add definitions from UEFI 2.7 Errata B standards doc for converting a
  text string to a device path. Added clearly missing 'e' at the end of
  Device to resolve mismatch in that document in
  EFI_DEVICE_PATH_FROM_TEXT_PROTOCOL element names.
