Some updates:

* QCA6390 support is now in v5.10-rc2

* pull request to linux-firmware sent, not yet pulled

* board-2.bin should be now used instead of board.bin

* there was some reorganisation in ath11k-firmware

Here are updated instructions on how to test ath11k:

# clone kernel
git clone -b v5.10-rc2 git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git

# clone firmware
git clone https://github.com/kvalo/ath11k-firmware.git

# Ensure below options are selected in the kernel
cd linux
make menuconfig
--> Select Device drivers
	--> Network device support
		--> Wireless LAN
			--> Enable as below
				<M> Qualcomm Technologies 11ax chipset support
				<M>       Atheros ath11k PCI support
				[*]       QCA ath11k debugging
				[*]       QCA ath11k debugfs support
				[*]       ath11k tracing support
				[*]     QCA ath11k spectral scan support

# Build and install the kernel and kernel modules

# Install firmware
cd ../ath11k-firmware
sudo mkdir -p /lib/firmware/ath11k/QCA6390/hw2.0/
sudo cp QCA6390/hw2.0/1.0.1/WLAN.HST.1.0.1-01740-QCAHSTSWPLZ_V2_TO_X86-1/*.bin /lib/firmware/ath11k/QCA6390/hw2.0/
sudo cp QCA6390/hw2.0/board-2.bin /lib/firmware/ath11k/QCA6390/hw2.0/
