The problem is not there, the problem is in places like: 
'ft2232_add_scan()' - which - assumes that tap_get_tms_path() always 
returns a 7 bit transition from state A to state B.  Evidently - one 
target/dongle combination The FreeScale mc1322x - and IAR Dongle - (Jeff 
Williams) has issues with this.

There was also a few other emails back and forth about OMAP and XSVF 
(xlinx) file playback where this caused problems.
