* Hermes download helper.
*
* This helper:
* - is capable of writing to the volatile area of the hermes device
* - is currently not capable of writing to non-volatile areas
* - provide helpers to identify and update plugin data
* - is not capable of interpreting a fw image directly. That is up to
* the main card driver.
* - deals with Hermes I devices. It can probably be modified to deal
* with Hermes II devices
