NAND driver - spare area ecc

[Sameer]

Hi,
I am working on NAND flash driver on TI's OMAP based board.
NAND is large page nand with 8bit buswidth.
I need to calculate ecc for the spare area data.
1.Does the current linux nand driver support ecc calulation for spare area
  with hw_ecc/sw_ecc enabled?
2.If not could any one suggest on what data of the spare area info I need to
  calculate ECC?

I am a begineer working on MTD driver. Please provide your
Valuable comments.


Regards,
