replace Nandflash on dm355 EVM

If I was going to replace the NAND device on my EVM, the first thing I would do is make sure that the new NAND device I buy is supported by the RBL (important if you plan on booting from NAND).  The ARM Subsystem Guide (http://focus.ti.com/dsp/docs/dspsupporttechdocsc.tsp?sectionId=3&tabId=409&familyId=1446&abstractName=sprufb3) list the NAND devices supported by RBL.

That said, you can try the nand_flash.out program (Alternatively DVFlasher is what I prefer, no CCS/JTAG needed), UBL, U-Boot, and Linux Kernel as-is, but if they do not work, it likely means you will need to modify them to add support for your particular NAND device.
