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.
