I am not aware of any ports in progress to this MIPS variant.

I have not looked at the IDT parts. The TX39 is an implementation of
the 32-bit R3000 architecture, the NEC VR4300 is an implementation of
the 64-bit R4000 architecture (although the eCos port only uses it in
32-bit mode), so two of the main MIPS variants are already covered.
If the IDT part corresponds to one of these then a port should be
fairly straightforward.
There is no MIPS16 or 64-bit support in eCos yet, nor any port to a
MIPS IV implementation. If you need any of these then a port would
involve significantly more effort.
You also need to take into account the effort that will be needed for
a board port to whatever hardware you intend to use, plus any device
drivers that may be needed.
