Comment 2 for bug 1993609

Enabled the focal-proposed repo in the setting, ran apt-get update, and ran apt install linux-firmware, the linux-firmware is updated to 187.35, check the folder /lib/firmware/ath10k/QCA9377/hw1.0/, the firmware-sdio-5.bin is in that folder. And the wifi could work with this firmware on the imx6ull board.

Verification done.
