I'm not sure we are in sync about this. The whole point of the previous
discussion was to decide whether or not we should make full use of
the MTD stack or not. I think it was pretty clear on the fact that
people prefer to be close to Linux's architecture on this regard.

MTD being an abstraction of the type of memory, I don't get the
point in creating yet another command each time a new type of
device is supported. The fact that all the drivers of these devices
register to the MTD layer makes it trivial to interact with. So why
should we wait?


Thanks,
