    That makes some sense. Currently you have:

    source "drivers/mtd/Kconfig"

    We can certainly improve the behaviour later, it's true -- it's not the
    end of the world if we continue to have the whole of the MTD layer
    turned off on platforms with alignment problems for now.

    But still, it's HAVE_UNALIGNED_ACCESS which we want to depend on, not a
    newly-invented HAVE_MTD. And there are other places we really ought to
    be depending on HAVE_UNALIGNED_ACCESS too.
