While I'm not sure about using jtag, we designed a background debug module (BDM) that 
worked with gdb flawlessly.  We used this to program the internal Flash ROM.  It was 
always my intentions to write a gdb script to program the external Flash, as well, but I 
never got around to it.  It's definitely possible, however.
