f90d8d47 | 2 | * Hermes download helper. |
f482eb79 | 3 | * |
f90d8d47 | 4 | * This helper: |
f482eb79 DK |
5 | * - is capable of writing to the volatile area of the hermes device |
6 | * - is currently not capable of writing to non-volatile areas | |
7 | * - provide helpers to identify and update plugin data | |
8 | * - is not capable of interpreting a fw image directly. That is up to | |
9 | * the main card driver. | |
10 | * - deals with Hermes I devices. It can probably be modified to deal | |
11 | * with Hermes II devices | |
