Which helpers are those?

$ git grep -Ei "\Westatus_" drivers/acpi/apei/ghes.c

doesn't give me a single one. Maybe I can't grep.

And even if, calling it a "estatus core" and making it a separate thing is
just confusing and unnecessary.

Nothing wrong with that as long as you simply export common helpers and we
agree on how they're going to be shared. We do stuff like that all the time.

Yes, carve them out in a separate compilation unit and select it in your DT
glue and that's it. No need for a Kconfig item and calling it a "core" bla.
