We are in the progress of starting to implement u-boot and will need NAND support as well.
As it looks at the moment we will access the NAND flash not in page boundaries, but rather with arbitrary offsets. At the moment we are using something similar to the boot command with is still a adaptation from former armboot. We don't use ECC and also no FS, rather fixed addresses. However this has to change in the future, but for the moment we are just prototyping.
I hope you don't solder your chips on the board, cause bad blocks can be present in pristine chips fresh from the factory. This will NOT work, since a bad block anywhere in the range that you use means that you must replace the chip.
AS or the bad block cheeking, I would rather go for the relocation implementation rather than the erasing the complete chip.
Me too, but it's kinda tricky...
I am looking forward to see how your work progresses and might commit to it in the future as well if I can.
Looking forward to it too.
