I have told the firmware team numerious times that the board file should
be backwards compatible as it creates problems for upstream. And I do
try to keep everything in ath11k-firmware (and in linux-firmware)
backwards compatible, but if they are not please do let me know. For
other repos I cannot do much, if any.
