As of about eighteen hours ago, the ST-E CW1100/CW1200 WLAN device driver was merged into the Linus's mainline linux tree, culminating more than a yearlong effort to get the driver into shape.
I'm now trying to get official permission to have the necessary firmware included in the linux-firmware tree. This is stymied by ST-E's recent implosion and the fleeing of all of my former contacts, but I'm told the WLAN group will live on, most likely under the STMicro name.
There's also the open question of support for the CW1x50 and CW1x60 successor chips. I need access to hardware to do any meaningful development, and I have no idea where to obtain that.
Ah, it's a good day.
