WiFi interface not working on Wi-i.MX28, Wi-i.MX51 or Wi-i.MX53 Linux

If your Wi-i.MX28 boots up with a boot log message like:
Starting network.
modprobe: chdir( No such file or directory
Loading ath6kl_sdio module: [FAILED]
ifconfig: SIOCGIFFLAGS: No such device
Starting dropbear sshd: OK

your WiFi interface will not work. Root cause is, the WiFi driver ath6kl_sdio kernel module was not loaded, since the kernel version you build does not match an appropriate path in your root file system.

Fix: rebuild your root file system and deploy it to the module.

On a Wi-ME 9210, Wi-i.MX51 or Wi-i.MX53 similar message might appear reffering to ganges/redpine driver.
