Hi everyone,

I'm also interested in seeing this series resurrected and making progress
again. I'd be happy to help out in any way. It's not clear to me if it has
a current owner. If not, then I could start shepherding the patches with
their authorships intact.

I may be able to do some testing on an FPGA too.

Thanks,
drew
