3 | EFI_HASH_PROTOCOL as defined in UEFI 2.0.\r | |
4 | The EFI Hash Service Binding Protocol is used to locate hashing services support \r | |
630b4187 | 5 | provided by a driver and to create and destroy instances of the EFI Hash Protocol \r |
d1f95000 | 6 | so that a multiple drivers can use the underlying hashing services.\r |
