@Aeolus Yang / Kalle / QCA: Would it be possible to assign a variant string to
the Asus RT-AC58U?
I've attached the necessary bmi-board-id=16 and bmi-board-id=17 board
files to this mail as well. So, all that needs to be done is to add
them to the board-2.bin on your codeaurora / ath10k-firmware project.
Kalle: Can you please update the board-2.bin for the IPQ40XX on your
ath10k-firmware project on github?
https://source.codeaurora.org/quic/qsdk/oss/firmware/ath10k-firmware/plain/ath10k/QCA40XX/hw1.0/board-2.bin
It looks like this board-2.bin has support for a few more boards.
Thanks,
Christian
