Replace ramtest pattern to assist in DIMM configuration

This is developer's testtool. Output from a "rotate ones" -style
    pattern helps figure out how DIMM addresses are encoded or routed
    on a certain mainboard.

Scattered test should cover every data and address lines on the memory
    bus, but is probably limited to the first bank of first DIMM.
