| 339 | VendorCode data validation. VendorCode data is ignored or considered invalid if image\r | |
| 340 | validation failed. The function returns EFI_ABORTED if the data is invalid.\r | |
| 341 | \r | |

| 346 | Sensitive operations such as those wiping the entire firmware image and render the device to be\r | |
