Change 175454 by raj at raj_nand on 2010/03/07 15:47:34

	Initial import of the NAND simulator (NANDsim)
	
	This consists of the following elements:
	
	  o kernel side NFC back-end driver, which plugs into the NAND
	    framework APIs as if it were a hardware controller with real NAND
	    chips connected to it
	
	  o userspace control applicaton (/usr/sbin/nandsim)
	
	From user perspective, the NANDsim allows for imitating ONFI-compliant
	devices as if they were attached to the system via a virtual
	controller.
	
	The NANDsim allows to configure the simulated environment; among major
	features it lets the user perform the following:
	
	         * retrieve simulation(s) status
	  * add new controller instance
	  * add new chip instance(s)
	
	  * delete chip instance(s)
	  * delete controller
	
	  * start simulation (controller)
	  * stop simulation (controller)
	
	  * errors management (on/off ECC, error injection, bad block
	    injection etc.)
	
	  * capture and print activity log
	  * capture and print statistics
	
	  * dump simulation state to a snapshot file
	  * restore simulation from a dump file
