You don't set nand->options...
Don't you want a bad block table?
hmm... some question. a little confuse.
- I using all rest of nand as rootfs partition. do I have keep some space in nand for BBT?
The last block or so is marked reserved for the BBT.
- do I have to tell u-boot where is the BBT?
No, it's marked with a special OOB marker. If it isn't present, it will create it at the end of the chip.
- do I need some configure in linux kernel for BBT?
Set the nand->options flag, same as in U-Boot.
