Wait! It is possible to do this now:
Sven Eckelmann added support for extracting the variant from the DT.
"ath10k: search DT for qcom,ath10k-calibration-variant" 
So, if Thomas splits the EX6100v2 and EX6150v2 image. He could have
two separate dts. This way, each device can have its unique
"qcom,ath10k-calibration-variant" and both can share a single
@Thomas, it's possible to get the EX6100v2/EX6150v2 board.bin into
the official board-2.bin. The process is explained on the linux-wireless
It would be great if you could post the raw board.bin files there
