I've only removed srst_pulls_trst and comments that mentioned that (and
comments that were not very helpful)
4\/3!!

Subject: [PATCH] remove srst_pulls_trst from LPC2xxx target scripts
LPC2xxx do not require reset_config srst_pulls_trst. This can cause various
"strange" problems when flashing the chip, because "reset halt" actually allows
the chip to run for some short period of time and execute some code.
