Yeah, it isn't great. If it were just that, maybe it it is worth it (and a `DmaAddress` newtype, not just a typedef, could perhaps be nice anyway?), but if you think it will become increasingly painful later, then it may be best to focus on what matters. It is unlikely there is going to be actual users on a 32-bit platform, right? Cheers, Miguel
