The OpenPower Abstraction Layer firmware went through a couple
of iterations in the lab before being released. What we now know
as OPAL advertises itself as OPALv3.
OPALv2 and OPALv1 never made it outside the lab, and the possibility
of anyone at all ever building a mainline kernel today and expecting
it to boot on such hardware is zero.

In the event of an OPAL v4 that is for some reason not backwards
compatible with V3, "*no longer* supported" might not make sense. This
isn't a huge problem of course.
