[U-Boot] Creating partitions on NAND flash

Dear Afzal Nadirshah,

Look at the "mtdparts" command.

How about trying something like "grep -lr mtd_partition *" ?

Reading the documentation is usually pretty helpful.

I really recommend it.

See for example
http://www.denx.de/wiki/DULG/UBootCmdGroupFlash#UBootCmdFlMtdparts
and
http://www.denx.de/wiki/view/DULG/BootTimeConfigurationOfMTDPartitions


Also, you should definitely look into UBI support if you're using this
on NAND flash.

Best regards,

Wolfgang Denk
