    Poison the stack to uncover programming errors
    
    Code can easily make the mistake of using uninitialized
    values or, in assembly, mistakenly dereferencing stack pointers
    when an address is desired.
    
    Set the stack to a non-zero value which is also (by testing)
    a pointer which will crash coreboot if used. This poisoning
    has uncovered at least one bug.
