Lpc2000

I have solved my myriad of issues and filled in enough of my own
ignorance to get this thing working.  I have the code located in lower
sectors of flash with a loader located in the middle sector (Luckily
we have way more flash space than we need) that is never erased.
I download new code packets over the ethernet interface and assemble
the new code to the upper flash.  I then copy them to the lower
sectors via RAM and power cycle (to be replaced by a WDT timeout).

I just have to add some CRC checks etc.

Thanks again for the helpful tips.
