> There is an ID collision between the JV and RV families. Both chips are
> very similar in practice, it is mostly a matter of electrical
> differences (mostly power consumption being lower).
> 
> As a significant difference, RV chips identify themselves as supporting
> The new SFDP (rev F) field which forces an alternate write SR2 opcode
> (0x31).
> 
> Since they share the IDs but not the names, we must hide the names using
> a fixup.
