ConnectME as JTAG controller

I wonder if someone is already implemented JTAG controller based on ConnectME.
The idea is to allocate 4 of GPIO lines for general JTAG interface to

  1. control external FPGA-based devices by implementing boundary scan primitives in them (like BSCAN in xilinx)
  2. test data taking at the rates of several hundred KBytes/s
  3. configuring FPGA devices using STAPL or SVF/XSVF files.

I have developed this functionality couple of years ago on ColdFire M5235BCC, but the ConnectME 9210 looks much better for that, it is 3 times smaller and 4 times cheaper.
