2 Framework SMM Status Code Protocol on PI SMM Status Code Protocol Thunk.
3
4 This thunk driver locates PI SMM Status Code Protocol in the SMM protocol database and
5 installs it in the UEFI protocol database.
6
7 Note that Framework SMM Status Code Protocol and PI SMM Status Code Protocol have identical protocol
8 GUID and interface structure, but they are in different handle databases.
