i have a r7800 running. consider to use the board.bin file which is
stored in flash memory of the r7800.
there are 2 stored for both cards. you need to patch ath10k to use
different board.bin files for each card.
this is a log from a working r7800 running dd-wrt. the failed to fetch
board data error is normal. it will use api1 board files then which i
provide on fs based on the board data stored in flash memory

What seems strange is that only the call bmi_execute with
BMI_PARAM_GET_EEPROM_BOARD_ID is timing out. So by just
ignoring the -ETIMEDOUT result from:
ret = ath10k_bmi_execute(ar, address, BMI_PARAM_GET_EEPROM_BOARD_ID,
&result);
in ath10k_core_get_board_id_from_otp() the device will initialize and work.
This begs the question, what is so special about the BMI_PARAM_GET_EEPROM_BOARD_ID
at that time for the QCA9984? Does the device need some extra msleep time after
the OTP has been uploaded? Or is the BMI_PARAM_GET_EEPROM_BOARD_ID not
implemented/has a different ID, etc... ?
Thanks,
Christian
