The 2410's NAND flash controller generates ECC codes (3 bytes ECC per each 512 bytes data). Are there any plans to incorporate hardware ECC support into this driver? Specifically, I guess that would mean adding "hooks" so the hardware-specific driver could handle the ECC parts (I only had to make a few small changes to nand.c to get this working for the 2410.) If there's an effort underway in this area, I'd be happy to participate in the development.
