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, -Sameer
