Even if you haven't partitioned your nand flash, you will probably find 
that for instance your nor flash is /dev/mtdblock0 and your nand flash 
then may be /dev/mtdblock1, assuming don't have any partitions in the nor 
flash. I.e. even without partitioning, each flash chip has its own 
/dev/mtdblockn device. This is especially true when the devices are not 
the same type (nor vs. nand). If you have several nor devices of the same 
type, depending on your mtd configuration, they can be concatenated to one 
single /dev/mtdblockn device.
