Only fs/yaffs is needed there plus a config/makefile patch to use it.

It might be that more than the nand bit of mtd is required. To be honest I have forgotten how patched the mtd tree is. A diff against a stock kernel would help. I hope you aren't mixing mtd distros. They tend to go as a single unit. Onto what are you grafting it?

lib is slightly surprising.

This must be an oob spare area problem. There may be "bad stuff" in the oob spare area that needs erasing. If you erase the nand completely and mount it (I hope its not your rootfs) there should be only lost+found and free space. If df shows lots spare then the problem is very probably a mismatch between ecc versions.

This is indeed perplexing and should have nothing to do with pxa. Charles?
