I guess the reason you're doing it like this, and not using a simple C

Yes, there's references in asm files.

Do we use similar mechanisms in other places?

I'd be surprised if we weren't, though off the top of my head the other
examples in arm64 are the sysregs and the hwcaps which are both ABI and
don't really benefit in the same way.

Would introducing a generic way to generate headers with definitions
from a C enum be worthwhile?

There must be some other arch which could use one at least.
