A number of ISPs have broadband packages that include a free Technicolor router. Supporting these routers could potentially benefit many users. Technicolor routers have firmware based on OpenWrt, so it's probably relatively easy to support these routers. I've raised a feature request here https://bugs.openwrt.org/index.php?do=details&task_id=3377
In the link below, it mentions that
Technicolor was even listed as an OpenWRT "gold sponsor"
I assume OpenWrt could get some help from Technicolor with porting? I think Technicolor would also benefit from having their hardware supported by upstream.
The bugtracker is for bugs, not feature requests and even less requests for new device support.
To the best of my knowledge Technicolor likes to use Bradcom SOCs, which would mean no support for xDSL, FXS/ DECT and WLAN ever. Using an OpenWrt derived SDK (which typically use a heavily butchered up, old, kernel with proprietary drivers) does no imply kernel-/ driver availability - and even less support with real OpenWrt.
