The early setup code for the ColdFire 53xx platform accesses variables
before the RAM and other system initialization steps may have taken place.
Currently it has 2 global variables that will end up in the bss section
that are accessed during this early setup. There is a special static RAM
stack setup at this time, but not necessarily the RAM where kernel data
sections will end up.

Even on system setups where RAM is setup by a boot loader the access
to the early setup variables is before the BSS section has been initialized.
This can potentially corrupt a ram loaded root filesystem that sits in that
memory area before it has been moved.

These 2 variables are not used at all after being set, and can just be
removed.
