[meta-ti] Gumstix Wifi

[joshua.marinacci at nokia.com]

Thank you everyone for your help. I finally got it working. After adding those extra recipes, doing the usual wifi config with /etc/network/interfaces and wpa-supplicant, and running depmod -a I was able get everything in place. Adding the magic firmware files extracted from Gumstix's pre-built distro was the last piece of the puzzle. When I next rebooted I was already on the network.  

So, my question now is "what's up with those sd8686* firmware files? If they are required then why aren't they a part of meta-gumstix?  Is it something special that can only be legally downloaded from Gumstix.com? 

thank you everyone.
