Dear all,
I have a driver for 4MB NOR flash ,I want to ungrade that code for 8MB NOR
flash.I have seen through the datasheet ,the working of both the flash are
same(erase steps,ID steps)as they are both EON company flashes.Can i use
the same driver for 8MB by changing device id.
With regards,
Keerti

You don't change the device ID. You add a new entry for the new device
ID.
You might also need to fiddle with the MMU setup for your target to
allow you to access the extra 4MB of memory space.
