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?
You can chose any setting you like. It's just that low boot is usually the most efficient and flexible one, as it allows to put the U-Boot code at the begin of the flash memory with room to grow after it, so you don't have any nasty gaps and it's trivial to change flash device sizes.
What are the other problems? I believe the TQM8xx ports do (or, at least used to) use this address.
See previous postings. And no, TQM uses 0x4000.0000, not 0x0400.0000.
