[Kalle Valo]

From: Kalle Valo <quic_kvalo@quicinc.com>

Use firmware mode 2 with QCN9074 to reduce host memory usage. Please review.

v3:

* new patch: ath11k: add ab to TARGET_NUM_VDEVS & co

* remove now unused ATH11K_QMI_TARGET_MEM_MODE_DEFAULT

[PATCH v3 1/2] ath11k: add ab to TARGET_NUM_VDEVS & co

[Kalle Valo]

From: Kalle Valo <quic_kvalo@quicinc.com>

The next patch changes TARGET_NUM_VDEVS to be dynamic and need access to ab.
Add ab separately to keep the next patch simple.

Compile tested only.

[PATCH v3 2/2] ath11k: Change qcn9074 fw to operate in mode-2

[Kalle Valo]

From: Seevalamuthu Mariappan <seevalam@codeaurora.org>

In mode-2 QCN9074 firmware uses 15MB of host memory and firmware
request 1MB size segements in QMI, whereas in mode-0 firmware
uses 45MB of host memory and each segment is of 2MB size.
In mode-2 firmware operates with reduced number of vdevs and peers.

Tested-on: QCN9074 hw1.0 PCI WLAN.HK.2.4.0.1-01838-QCAHKSWPL_SILICONZ-1
