According to the manufacturer, the board itself should identify itself as
chip_id: 0x2, chip_family: 0xb, board_id: 0x301, soc_id: 0x400c0200
I have therefore dumped the memory region with the qmi response via kgdb. You
can easily see that the response has following sections:
* 0x02 (len 4) - resp
* 0x02 (len 4) - resp
* 0x10 (len 8) - chip_info
* 0x12 (len 4) - soc_info_valid
* 0x13 (len 21) - fw_version_info
* 0x14 (len 77) - fw_build_id
* 0x15 (len 1) - num_macs
* 0x16 (len 4) - voltage_mv
* 0x17 (len 4) - time_freq_hz
* 0x1A (len 8) - ????
So the section 0x11 with the board_id is completely missing. For some reason.
