Memory used by RedBoot and "normal" applications do not overlap. The MLT
files imply that they do, but this is because RedBoot is just a ROM
application and the MLT setup is to allow for any application to use all
available resources.
In general, RedBoot uses a chunk of low memory (128k is typical) and
RAM based applications are set up to load just above that and use the
remaining memory.
