    Actually, checking for the presence of all possible perverted
mapping
props doesn't seem a good idea -- it's simpler to check for the
presence of
one prop (like "direct-mapped" I was thinking about, or maybe
"simple-map").

Or more simply... if it's not a direct mapping, it doesn't have a 
ranges
property and can't be walked down by conventional means.

That establishes that the flash address space is mapped 1-1 into
the host address space; however it doesn't say anything about
swizzling or interleaving or endianness etc., which are important
for NOR flash memory because of how the command sets work.
