NAND flash booting problem, OMAP3530

hi all

i am working on OMAP3530 and  256 MB NAND flash used for booting.

my question is,

how to use some portion of NAND flash as a mass storage device?

i have done some changes in /arch/arm/mach-omap2/board_omap3devkit8000.c to create extra mtd partition.

actual NAND flash partitions are

0x00000000-0x00080000 : "X-Loader"
0x00080000-0x00260000 : "U-Boot"
0x00260000-0x00280000 : "U-Boot Env"
0x00280000-0x00680000 : "Kernel"
0x00680000-0x10000000 : "File System"

After creating one more extra partition called EXTENDED PARTITION

0x00000000-0x00080000 : "X-Loader"
0x00080000-0x00260000 : "U-Boot"
0x00260000-0x00280000 : "U-Boot Env"
0x00280000-0x00680000 : "Kernel"
0x00680000-0x01940000 : "File System"
0x01940000-0x10000000 : "EXTENDED PARTITION"

i created uImage and working fine if booting from SD Card.

but not booting from NAND flash

i have attached the console output file, please refer and suggest me..

thanks and Regards
