| * Images, measured during the boot process, have some associated metadata. |
| * One of these types of metadata is the image identifier strings. These macros |
| * define these strings. They are used across the different measured boot |
| * backends. |
| * Note that these strings follow the standardization recommendations |
| * defined in the Arm Server Base Security Guide (a.k.a. SBSG, Arm DEN 0086), |
| * where applicable. They should not be changed in the code. |
| * Where the SBSG does not make recommendations, we are free to choose any |
| * naming convention. |
| * The key thing is to choose meaningful strings so that when the measured boot |
| * metadata is used in attestation, the different components can be identified. |
