Because it uses a proprietary comms mechanism and Keil only provide an RDI
interface IIRC. Hence, there is zero possibility of hooking it into
OpenOCD.

4-wire JTAG is standard except that when implemented by CPU vendors
non-standard features creep in (e.g. RTCK). There is no standard JTAG
connector because each and every JTAG header features extra pins for other
fluff. Hence there's a good reason to make a single-function device which
reduces production costs.

However, I have written a STAPL interpreter (i.e. it parses and runs STAPL
files) which runs with a CrossConnect or FTDI devices. You can use this to
program things other than ARMs.
