The TI C6000 does some amazing pipeline optimization, which seems to be missing from the GCC compiler. Anyway, using CCSV6 is no big deal, but support for RPMSG/REMOTEPROC on this processor is a big issue. The source is difficult to follow and my guess is we would need input from the original authors to do this work.
