$ cat /tmp/x.json
[
         {"names": ["bus=snoc,qmi-board-id=stinkyboard"], "data": "board_stink.bin"}
]


$ ls -lh board_stink.bin
-rw-rw-r-- 1 konrad konrad 19K Mar 13 16:42 board_stink.bin


$ python3 ~/qca-swiss-army-knife/tools/scripts/ath10k/ath10k-bdencoder -c /tmp/x.json -o board-2.bin
board binary file 'board-2.bin' is created

I believe Kalle aggregates these boardfiles and then uploads a big
combined board-2.bin to linux-firmware nowadays?
