The attached patch adds a -j option that allows adjusting JTAG
daisy-chain parameters. The argument to the option is a
comma-separated list of four numbers:
-j ub,ua,bb,ba
ub -- units before
ua -- units after
bb -- bits before
ba -- bits after
I cannot test it except by passing -j 0,0,0,0, and cross-checking that
specifying any other parameters results in the ICE being unable to
communicate with the target.
Documentation update is still missing.

Never trust an operating system you don't have sources for. ;-)
