Yeah, the whole logic of it is flawed. A saner alternative that
also allows for work-out blocks would be static partitions with
a statistical guarantee that they contain enough good blocks.
There's where this idea started:
However, switching to such a model on GTA02 would mean to
rearrange partitions, which is messy at best.

As far as I remember, u-boot doesn't mark worn-out blocks.

Oh dear. Somebody meant well, but ... :-(
So this happened about three weeks ago. I've fixed it now.
Hmm, now what do we do with the victims of this ...
