Yes; this isn't uncommon for some of the really old device models. It should definitely have one added. You are correct also that the timer in the pflash_cfi01 model is dead code -- it has always been so, since the device was added in 2007. The reason it is there is that pflash_cfi01 was created as a copy-and-hack of the cfi02 device. In cfi02 we do use the timer, as a way of simulating "make full-chip and sector erases take a guest-visible amount of time rather than completing instantaneously". cfi01 doesn't do that (and I think may not implement anything other than block erase), but the timer initialization code was left in rather than being deleted as part of the copy-and-hack. thanks -- PMM
