The size of this device is depends on the size of the mtdram (not 
related to mtdblock, I think). It can be configured easily by kconfig: 
you can specify the size of it and its erase block size.

Nandsim is also configurable but unfortunatelly not from kconfig. If I 
am right you have to edit sources by hand. Firstly in the source of 
nandsim you have to specify a chip ID. You have to look up this ID from 
  nand_ids.c (if you found an appropriate NAND chip) or you have to 
define an own one.
