I agree; I avoided doing that for now because I was uneasy about 
duplicating device nodes for SOC devices covered under the non-OF 
platform bus via code in sysdev/fsl_soc.c.  It probably won't cause any 
real problems unless a single device matches drivers on both buses (in 
which case the of_device driver would probably be calling 
of_platform_device_scan() anyway), but still...

What I'd really like (long-term, of course) is if platform_device and 
of_device were merged, with device tree support (or at least a means of 
passing on properties that *could* come from a device tree without 
special glue code that knows about each property) in arch-neutral code; 
the mechanism for discovering devices ideally shouldn't depend on the 
CPU's instruction set.

Why only spider?
