u-boot version: u-boot-2010.12
My OR and BR register values(according to our memory map): BR0 0xFF800C21 OR0 0xFF800396 BR1 0xE8000801 OR1 0xFFFF8074 BR2 0xE8009001 OR2 0xFFFF8074
after defining VERBOSE_DEBUG in drivers/mtd/nand/fsl_elbc_nand.c i gave sacveenv command, igot below logs. please go through that and resolve asap.

Dear Manukumar,
Hello,
CCing someone who might actually help you, CCing the uboot mailing list, please keep it that way.
i can able to detect nand flash. but i had an issue that i could not do operation(Read/write) on nand flash. i tried to erase the nand flash i got the error as below:
NAND 32MiB 3,3V 8-bit: MTD Erase failure: -5 NAND 32MiB 3,3V 8-bit: MTD Erase failure: -5 NAND 32MiB 3,3V 8-bit: MTD Erase failure: -5 NAND 32MiB 3,3V 8-bit: MTD Erase failure: -5
even if i try to saveenv then also is not saving the envionment variables
processor used: P1012 nand flash: samsung K9F5608U0D
please reply ASAP.

What version of U-Boot is this?
How are you configuring BRn/ORn for this chipselect?
Could you define VERBOSE_DEBUG at the top of drivers/mtd/nand/fsl_elbc_nand.c?
