Sorry, but I fail to understand you here. Please give an example.

Such a small sentence for such a big and good news. So for the record:

YOU HAVE TO USE MICROCODE VERSION 2.0!!!

(Sorry for shouting.)

Yes, this is the way to current implementation handles the "cp" command. At 
least in the common CFI flash driver.

Not sure if this is welcome. The "cp" command is not a (NOR) FLASH specific 
command, but a memory subsystem command. So a change here would also affect a 
copy from memory to memory too.

But sure, technically it is possible to do. You could implement this behavior 
(e.g. print a dot each second while copying) and send a patch to the list.
