Ah, I forgot to mention that everything under "testing" directory is
work-in-progress, and might break backwards compatibility. To keep
things simple I now removed all backwards incompatible files from my
ath11k-firmware. Also now there's a proper board-2.bin for QCN9074,
hopefully that works better. Do let me know if you have any issues.
