I guess I will try and get my ft2232.c patch in by end of the day, as 
promised earlier, and add this stuff in too:

https://lists.berlios.de/pipermail/openocd-development/2009-March/005123.html

But I will not be able to test that usb chip.

Also, there was buffer overrun patch hanging around here also that I 
think we should add.  This is the ft2232 chip's buffer, not openocd's 
buffer which is a different issue that will likely not be addressed 
fully in my patch.  But as I said earlier, the asserts() should trap it, 
which is better than seg-faulting.

The new driver will work with the short clock tms_seq table, but I had 
to extend the number of clocks while in reset back to 7 and change two 
other entries, namely the paths from RESET to either DRSHIFT or 
IRSHIFT.  Jeff's table was a no go for me out of the box on ARM9 with 
ft2232 usb cable.  To some extent the clocks while in RESET might simply 
be a way for the chip to wake up from being hit on the head, sort of a 
timing delay.


This means I have a jtag.c, ft2232.c, and xsvf.c patch coming.  I will 
provide the first two soon.  With xsvf.c to follow in another day or so.
