I don't think anyone has submitted any source patches to provide it.
There has been some discussion in the past......

That would be great. If you would like to submit it as a patch someday,
that would be even greater :-). What are you connecting at each end
of the port? NMSI, TDM, custom software?
Another part of your project will be writing a driver. In the past,
the accepted suggestion was to not modify the uart driver, as that
is a _uart_ driver, not an SCC driver. You can use that as a model
to create, say, hdlc.c......Then just ensure you don't try to configure
the SCC in both places (and there may need to be a little knowledge
about each one in every driver).
