Either you or me misunderstand the purpose of these weak accessor functions. > weak accessor functions, those work transparently.

Either we have flash memory; then it is a mandatory requirent that we can access the flash memory using all memory accessing commands, including "cp", "md" etc. This is not the case on any devices that require additional address switching, like on processors that use things like bank switching signals in addition to the normal address lines. Otherwise we have some form of storage device, which cannot be accessed with commands like "cp", "md", or "erase". NAK.
