| 24 | * Images, measured during the boot process, have some associated metadata. |

| 26 | * define these strings. They are used across the different measured boot |
| 27 | * backends. |
| 28 | * Note that these strings follow the standardization recommendations |
| 29 | * defined in the Arm Server Base Security Guide (a.k.a. SBSG, Arm DEN 0086), |
| 30 | * where applicable. They should not be changed in the code. |
| 31 | * Where the SBSG does not make recommendations, we are free to choose any |
| 32 | * naming convention. |
| 33 | * The key thing is to choose meaningful strings so that when the measured boot |
