I'm asking because Marc-Andr=C3=A9's work changes many values to add a more useful replacement. I think we should deprecate @type. I'd like to find out whether we need to preserve the values for the deprecation grace period.

These are ast2700-a1, ast2700-a2, and several riscv CPUs. A fix for the latter has been queued. > 1.
