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