*
* Changes:
* 08/22/2009 - DMK
* Analog test levels changed from 700/150 to 610/130
* (passband/stopband)
*
* 01/30/2019 - Stacy Olivas <[email protected]>
* Fixed CM119 chipset and added CM119A/B chipset detection
* Fixed initialization/error messages at startup
* Added ability to adjust levels per chipset type
*
* 02/11/2019 - David Kramer <[email protected]>
* Lowered #define C119B_ADJUST to compensate for lower 'B' version
* chip output.
*
* 05/08/2019 - David Kramer <[email protected]>
* Raised #define C119B_ADJUST to compensate for "fixed" B versions
*
* 05/10/2019 - David Kramer
* Fudged passband levels for 700Hz when mixed with 5khz. Readings are
* too high for some strange reason, but URIs seem to work ok.
*
* 09/18/2023 - Danny Lloyd, KB4MDD <[email protected]>
* moved user memory from address 6 to address 51 - we cannot overwrite manufacturer data
* added ability to dump the EEPROM memory
* added ability to list manufacturer settings
* added ability to program manufacturer settings

* \brief EEPROM memory layout

* The CM108 and CM119 reserves memory addresses 0 to 6.
* The CM119A reserves memory addresses 0 to 44.
* The CM119B reserves memory addresses 0 to 50.

* The usb channel drivers store user configuration information

* The user data is zero indexed to the EEPROM_START_ADDR.
*
* chan_simpleusb radio does not populate all of the available fields.
