Prabhaharan, Which kernel are you using? There should be a NAND driver included already which will help you access NAND flash.
You can use the nandwrite mtd-util to write to NAND Flash.

For example, let’s say the NAND memory address range is 0x02000000 to 0x3000000. In this case, I am trying to write the data in to the base address 0x02000000 from the Linux OS using davinci_writeb(val,0x02000000). But, this gives an error message as “Unable to handle kernel paging request at virtual address e1400010”. Did anyone face the similar issue? Is there any other way to write the data in to the specific location in the NAND. Please reply. Thanks a lot in advance.
