To report nand bad blocks, I have been using cmd 'nand bad' from uboot. What Linux cmd will get thesame report from a Linux prompt? I'm using Denx eldk4.2 on an AMCC PPC440EPx. I'm not sure what nand chip.

Hmm, I think this utility does not exist, and you need to implement it, but I am not 100% sure.
