Do we really need it? I turned my previous question around - why does the
_map_ driver need to know about it? 

You've said, and I agree, that the map driver won't necessarily know the 
size of the chips within the area, so it can't know how the aliases are 
arranged and remap the space itself. 

So the flash probe code needs to work that out for itself, and as 
soon as the cfi_check_chipalias() function does something other than 
'return 0' that'll be fine. Presumably you have something similar.

Having worked out where each chip starts in the map, and recorded its start 
address in the per-chip data structure, why does the flash driver need to 
tell the map about it? Why not just use the 'correct' addresses?

Fixed. Thanks.

Hmmm. How about a char * ?

You mean a static initialiser that ends up in the data segment rather than 
kmalloc'd? What does it do for us?

I was aware of the netdev name changes - but that changed from a char * to 
a constant-length char[] to allow name changes to work without overflowing 
the original string.
