[yocto] Problem installing ath10k firmware

[Todd Efflam]

Hello,
We're having a problem getting the ath10k firmware to run with a new
wireless card.  The card uses chip QCA9882.  We've tried installing
ath10k firmware using:
IMAGE_INSTALL_append += linux-firmware-ath10k

in combination with the following kernel configs:
CONFIG_FIRMWARE_IN_KERNEL=y
CONFIG_EXTRA_FIRMWARE_DIR="/lib/firmware"

we tried adding
CONFIG_EXTRA_FIRMWARE="ath10k/QCA988X/hw2.0/firmware-2.bin
ath10k/QCA988X/hw2.0/board.bin" but this failed as it wasn't able to
locate the files.

After building, we receive the following error when booting our cpu:
ath10k: Could not fetch firmware file 'firmware-2.bin': -2

We then realized lib/firmware.... contained firmware-4.bin and
firmware-5.bin instead of firmware-2.bin, but after copying
firmware-4.bin to 2 we still received the same error from our cpu.

Has anyone had success getting ath10k to run with firmware-2.bin?  Any
help would be appreciated!

Best,
Todd
