    My general idea about future Cell based products is that we make the
    changes to the platform code at the time we add new code. Of course,
    a number of companies are working on designs that I have no insight in,
    so I'll just wait what comes, but at least I've tried to make it
    easy to add the stuff that I know about.

    Yes, this one is a bit odd. On the one hand, it is very generic and could
    be used for any future open firmware or flat device tree based system
    (even non-PowerPC). On the other hand, it works only on one particular
    board design currently.

    I don't really care about where this is put, ranging from:

    arch/{ppc64,powerpc}/kernel/of_nvram.c, meaning that everyone using the
    flat device tree can just add an "nvram" node that will work with
    this driver.

    arch/powerpc/platforms/cell/cellblade_nvram.c, to keep it specific to
    the one design that we have, assuming that future Cell based
    designs will use something else.
