I tried another rootfs without rfkill, met the same issue when doing
ifconfig wlan0 up, just like 'rfkill unblock wlan'.

I looked into a bit more about the error and found there's CMD timeout
on the bus during SDIO
command transfer.

I'm not sure how this happened, whether caused by host side or wifi driver side.
But for the host, i tried this host driver with another WiFi
card(Atheros AR6103) with same kernel,
and it worked well. So the host driver seems more like ok to me.
Since i'm not familar with the WiFi driver, i wonder if you could
provide suggestion
from WiFi driver layer to see what the issue could be.
