I agree with you that the naming is really misleading - other devices  
which are not mtd's may suffer from the same problem of the lpb (in my  
case, I have an extra memory-mapped Ethernet chip which I didn't try to  
access yet...).

As it is actually a chip select property, what about defining an  
optional property like "cs-width = (8|16|32)" which defaults to 8 and  
may be added to each 5200 lpb child?

Just out of curiosity: what about the "localbus" of other Freescale  
chips (82xx? 83xx? Maybe others?)?

Thanks, Albrecht.
