    ddr: altera: Repair DQ window centering code · e026b984
    Marek Vasut authored
    The code uses a lot of signed numbers, which ended up in variables
    of unsigned type, which resulted in all sorts of underflows. This
    in turn caused incorrect calibration on certain boards. Moreover,
    repair the readout of the DQ delay, which was being pulled from
    wrong register.
