It looks like there was no update on the linux-firmware repository for
sd8801_uapsta.bin binary in the official linux-firmware tree.

I can share that I've tested: 14.68.36.p160 version with mwifiex driver
on 5.4.y kernel and the STA mode works.

The used NXP soc is imx6ull, and wi-fi is SDIO connected 88W8801.

However, there is the issue with AP mode. Please find attached logs and
reproduction procedure.

Is there any schedule for releasing new FW for this wifi chip?
