    OK, that's indeed useful to know, thanks.

    In your opinion, should there be a guarantee that accesses initiated
    by readl/writel/etc. will not be reordered?

    Alternatively, should device driver writers be required to put in an
    explicit statement (mb() or something similar) when they use
    readl/writel/etc. and want to prevent the accesses being reordered?
