    I have separated out the C71 platform driver pieces (patches 1 & 4) and
    posted a v2 for those.

    Appreciate any feedback on the core patches (patches 2 & 3) that add the
    minimal 64-bit trace support, as this also sets the direction for
    resource extensions. I can post the next version for those based on
    feedback.
