Please see Julius' comment in https://chromium-review.googlesource.com/c/chromiumos/platform/vboot_referen...:
> Let's not put these casts here. They are unnecessary for now, because we haven't allocated bit 32 or higher yet, so they'll always be 0 anyway, and once we do we'll have to stop using an enum anyway because enums can't be larger than 32-bit (I think?). So at that point we'll have to represent them as macros or something and then we should just define them ULL to begin with.

> We definitely don't want to be in a situation where you have to put this cast here or otherwise something is gonna silently break (because sooner or later someone would make that mistake), so we wouldn't build a system that requires that. Then there's no point in having the casts here either. (If you want to be extra proactive, feel free to already rewrite the field definitions now.)
