But what in concrete terms is that supposed to mean? It's currently just an essentially undocumented flag on a message rather than something operating at the level of a flash chip. That's pretty much where Russell's comments come from. > If I was using m25p80.c to talk to anything but an actual flash chip > it would get me quite worried. Sure, but at the end of the day it's just emitting standard SPI messages which don't know anything about flash. If those messages are a sensible interface here then why bother with the flag, we can just pattern match on the format of the message. If that doesn't work then probably this isn't a great interface and a separate, application specific interface makes more sense.
