My bad, wrt 0x0100 (I was more concerned about aliasing while writing 
the previous email), but my understanding is that typically MPC8xx ports 
of U-boot assume that HCRW is configured for the low boot option, don't 
they?

Agreed.

What are the other problems? I believe the TQM8xx ports do (or, at least 
used to) use this address.

Thanks,
Vladimir
