+ 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
