Which would mean that booting old kernels on new FW which defines those
reserved bits would cause that warning to fire erroneously.

So then we probably don't need it at all or we need to check implemented
BGRT version of the FW running to know which bits are defined by the
spec and which are reserved...

Also, does the spec really say that reserved bits must be zero? Or it
doesn't specify their value?
