[mc1322x] Building mc1322x contiki

[Umberto Manzoli]

Hi Jon,
  I had some similar problems some time ago, and I found out it was a
misplacement of (re)locations directives into the linker script.
Would be so kind to check your linker script  and see if all needed code
(and/or included by libraries) is assembled and relocated within 0x0040000
and
0x00400000 + 96K? Which is the output of a size command  (with -A -x
switches) on the produced elf executable?

Bye,
  UM
