No, the bad block list is not on the u-boot environment. The bad block 
list is in a different hidden area, which doesn't show up as a partition 
and thus is a bit harder to damage (it's in the four "fake" bad blocks 
at the very end of the NAND flash).

There's another "hidden" area, in the OOB bytes of the first NAND block, 
which points to the u-boot environment. If the partitioning is different 
(and the partitions are stored in the u-boot environment), it has to be 
adjusted to point to the u-boot environment (else u-boot cannot find it).

For more details, take a look at (which was written for the 
GTA01, but AFAIK the only relevant change for the GTA02 is the addition 
of the NOR flash and different partition sizes).
