David Kilroy | f482eb7 | 2008-08-21 23:27:51 +0100 | [diff] [blame] | 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 |
