    There is no real need to exactly define space for saving patterns for
    alternate memory test. It is much easier to allocate space on the stack and
    use it instead of trying to find out space where pattern should be saved.
    
    For example if you want to test the whole DDR memory you can't save patter
    to DDR and you need to find it out. On Xilinx devices DDR or OCM addresses
    were chosen but that means that OCM needs to be mapped and U-Boot has
    access permission there.
    
    It is easier to remove this limitation and simply save it on stack because
    it is very clear that memory test can't rewrite U-Boot and U-Boot has also
    full access to memory where runs from.
