I am not looking at this as I am busy but I have an idea or two

- CPU bug in 83xx CPUs which uses 0x110 as cold start vector.

- Misconfig of HRCW, don't know if you can change the reset vector that way
  but I guess you need to check.

I think a Freescale guy needs to look at this unless you can find something wrong
with HRCW
