Lpc2000

I now have eCos running on my IAR KickStart card
with a LPC2106. RedBoot also runs, though I wasn't
yet able to download a program in RAM and execute
it from RedBoot.

I had to correct some stuff in the bugzilla port
to get rid of compiler errors and warnings and get
the thing working.

A few of the things that still need to get done:

- Flash driver for the onboard Flash
- Clarify the PLL configuration code. Right now
  there's nothing "real" about the real-time
  clock...
- get eCos and an application compiled and working
  in thumb instruction set.
- etc.

How are the other people running eCos on the
LPC2000 doing? Maybe we should start contributing
to the bugzilla port at some point, instead of
doing our separate thing.
