I would like to know the status of this "tranparent" hardware ECC mechanism in the Linux source. I assume that you want to integrate this support there too, right? I couldn't find any reference to this in the current mtd/nand implementations and/or any reference to the MPC831x.
I have a Linux patch from Nick Spence for nand on the 831x, but it needs a lot of cleanup before I can submit it, which I haven't had a chance to do yet. It currently uses a rather ugly hack to get around the lack of transparent ECC support (as did the u-boot patch before I reworked it).
I'm asking, since the U-Boot nand code is based on the Linux mtd codebase, and we should try to keep features common between both source codes as often as possible.
Agreed, though when writing the u-boot patch I looked at the kernel source, and it appears to have already diverged quite a bit. When I get a chance to look at the 831x NAND Linux patch, I'll most likely implement similar transparent ECC support there.
