Hi Wolfgang, Thanks for the suggestions. I went through some of the documents. I found that the partitions and their offsets and partition names are provided in the .dts file. I hope I have understood it right.

Dear Afzal Nadirshah,

I would like to partition the NAND flash on a canyonlands board. As per my understanding, the partitioning is done using the "add_mtd_partitions" function in the file "drivers/mtd/mtdpart.c".
Look at the "mtdparts" command.
I also understand that the information about a partition is stored in the structure : "struct mtd_partition" . I could not find out where this structure is getting populated in the u-boot code.
How about trying something like "grep -lr mtd_partition *" ?
My aim is to add more such partitions on the NAND flash on my board. Any information regarding partitioning the flash is highly appreciated.
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
