    Boot space translation utilizes the pre-translation address to select
    the DDR controller target. However, the post-translation address will be
    presented to the selected DDR controller. It is possible that the pre-
    translation address selects one DDR controller but the post-translation
    address exists in a different DDR controller when using certain DDR
    controller interleaving modes. The device may fail to boot under these
    circumstances. Note that a DDR MSE error will not be detected since DDR
    controller bounds registers are programmed to be the same when configured
    for DDR controller interleaving.
