I had are look at that for another board. And I found out that they changed 
the size of various sections in the BDF and moved stuff accordingly. And the 
one in Kalle's ath11k-firmware repository is even using different IDs. This 
caused the ABI breakage which John described in the other reply.

No idea how the firmware is supposed to handle this. At the moment it is only 
clear that it didn't handle it :(

Kind regards,
