Attached is the kind of change that affects the platform code.  
Meanwhile if I was to morph the ts7250 driver my first step would be to 
trim a huge chunk of the platform specific code that's in the NAND 
driver and then at the same time get the ARM platform driver amended 
otherwise you end up with a NAND less board.

It's been hard enough to submit my TS-7800 patches and break them up so 
the different subsystems gracefully get added.  To modify the existing 
ts7250 driver I would have to take on the tinkering and submission 
cycles with the TS-72[056]0 (when I don't own one) too.  As I so far 
have gotten zero feedback[1] from the community this seems to me the 
*only* way I can work on my patches with a view for upstream submission.

This way, with a separate driver, when things finally/if-ever get 
accepted nothing breaks.  I think the changes also being made are easier 
for someone

If you know of a way that the MTD folk are willing to tinker with the 
ARM subsystem code and vice versa (last time I was told by the ARM 
people to break up my MTD stuff and submit it to you guys separately) 
then I'm listening.

I'm stuck in a rut and it really is wearing me down...I'm not even a 
embedded developer, just a network packet pushing perl monkey who just 
wants to get his router working :-/

Cheers

[1] and I still do not understand why in the ts7000 mailing list there 
	is all this work on a seperate patch set for ts72[560]0 support 
	when they apparently do not have a NAND driver even?  Any ideas?
