I use the command:

   nboot.i 20000000 primary

primary is in my mtdparts environment variable:

   mtdparts=nand:7m at 0m(primary),7m at 7m(secondary,2m at 14m(config)

mtdids is
   nand0=nand

partition is
   nand0,0

You're going to have to configure your nand flash in your board config
file.  I believe there are sufficient examples for you to read.
