MIPS® Creator CI20 / clang/llvm?

Is anyone actively working on FreeBSD for the MIPS® Creator CI20?

What is the current status of building FreeBSD-MIPS using clang/llvm?
 I found some information here:

    https://wiki.freebsd.org/BuildingFreeBSDWithClang

but it is note that the information is out of date.

I asked Kai Nacke about his slides from FOSDEM '15:

    http://llvm.org/devmtg/2015-02/slides/kai-assembler.pdf

which mentions the JZ4780 and "> 60 new instructions (MXU extension)".
 Kai told me that he used the JZ4780 as an example but he is not aware
of anyone working on integrating the new MXU instructions.

I have a CI20 Revision B (purple circuit board) and am willing to
experiment with it.  I don't have access to any other mipsel hardware.
 I do have access to a reasonably quick x86_64 which I could use for
cross-compilation or simulation.

Any suggestions to which versions of clang/llvm and target
(mipsel-portbld-freebsd10.1?) to try?

Thanks in anticipation
