Abstract: \r
  EFI_HASH_SERVICE_BINDING_PROTOCOL as defined in UEFI 2.0.\r
  EFI_HASH_PROTOCOL as defined in UEFI 2.0.\r
  The EFI Hash Service Binding Protocol is used to locate hashing services support \r
  provided by a driver and create and destroy instances of the EFI Hash Protocol \r
  so that a multiple drivers can use the underlying hashing services.\r
  The EFI Service Binding Protocol defines the generic Service Binding Protocol functions.\r
