QCA9984 firmware crash

[Sergey Stepanov]

Hi

I'm porting ath10k drivers to run on a non-Linux environment (embedded
PowerPC with custom RTOS). At the moment only QCA99X0 part works
(somehow).

I have problem with running driver for QCA9984 part: firmware loads,
and during the boot if crashes with log:

 ath10k_debug_print_hwfw_info()    : qca9984/qca9994 hw1.0 target

I also tried firmware ver 10.4-3.3 without success: same symptoms an
same faults.
I used driver sources and firmware from git repositories? listed on
http://linuxwireless.org/en/users/Drivers/ath10k.

I can provide more information (logs) to help to figure out: where the
problem is?
