But it is just a plain cable without logic, i presume i.e. there are no
hardware modifications necessary for the TI board nor the iEi
mainboard, right?

How did you obtain the flashrom source (file archive, subversion,
git...)? Depending on that the way to obtain a usable diff/patch vary a
lot. If you need further help you can also ask us on our IRC channel,
#flashrom on freenode, available also via this website:

Your assumptions are correct. No hardware modifications were made, I  just
had to jumper the TI board appropriately (basically disconnecting the MCU
from the JTAG port).

I based my modifications on the last release, but as these are just a few
additional lines to the sources, I could easily base those on trunk or any
other revision. I'll see how far I can get, I'll be gladly asking for help
then.
