Think of JTAG as I2C for testing. It doesn't define what it can do,
just a logical interface that allows a uniform channel for communication.

boundary scan capabilities: @par

OpenOCD does not presently have clear means of using JTAG for boundary
scan testing purposes; however, some developers have explored the
possibilities. The page contains information that may be useful to
those wishing to implement boundary scan capabilities in OpenOCD.
