Update: with the current wlanmdsp.mbn I'm getting the following error 
from the DSP:

[   22.468121] qcom_q6v5_pas 6080000.remoteproc: fatal error received: 
EX:kernel:0x0:SigVerify:0x173:PC=0xc10dd460

The board is not fused, but the signature format was changed (and so 
were some of the fields).

It seems we will have to provide the updated file somehow to 
linux-firmware. What would be the preferred way for us to do so?
