Yes can confirm - I've recently been contacted be end-users of the
module. It provides effective software based echo cancellation for
users of the Asterisk IP-PBX.

I had picked up this patch at first, but now took a closer look and found no
users of this module. It sounds to me like we should remove the entire
directory rather than just the blackfin portion.
Adding the original authors to Cc for clarification.
The echo "driver" is used by Asterix systems. It seems to be the only
driver that ended up getting merged upstream from that huge mess. So
there are users of it, or at least there were, I don't know how popular
Asterix is these days.
