IPQ6018 issues

[Robert Marko]

Hi,

I am trying to use ath11k on multiple IPQ6018 and IPQ6010 boards,
unfortunately, they will all fail like this:

I added most of the prints to figure out where it dies.
If cold-boot calibration is enabled then it will die on the
ath11k_qmi_process_coldboot_calibration(), to be exact on the

But, if cold-boot calibration is disabled then ti will fail in
ath11k_core_qmi_firmware_ready at or after ath11k_crypto_mode switch.

A big issue is that it will crash the board and it will get stuck in
SBL, only removing the power will help.

The hardware I tried on is:
* Wallys CP01-C1
* Wallys CP03-C1
* Alfa AP1800C-AX PRO

I also tried fw versions from 2.1.0.1 to 2.5.0.1-R2

Does anybody have an idea how to solve this?
