I don't believe that Philips publish anything that tells you how to
program the flash on the LPC, other than by using the bootstrap loader
or by calling a set of routines in the rom yourself (which the BSL
itself uses).  As such, it is impossible to program the flash (read:
nearly impossible) using pure JTAG.  Certainly, I believe Philips can
change the flash controller or technology without changing the
programming interface, so even if you did reverse engineer the bootstrap
loader to figure out how to poke the flash controller, it's not
guaranteed that the flash controller remains static across revs of the
silicon, but the API will.
