[PATCH] [ARM] kirkwood: combine support for openrd base/client support

[Dieter Kiermaier]

Hi Alexander,


> Based on the work done by Dhaval Vasa to add OpenRD Base support (and 
> the unmerged Client) support, this patch adds support for the 
> Kirkwood OpenRD Client board.
> 
> I was 'inspired' by the work Hartley Sweeten had done in flattening 
> mach-ep93xx into a single setup.c file; as there is really not much 
> difference between the OpenRD Base and Client boards I think it is 
> appropriate to do the same here.

shouldn't it be enough to have the if(machine_is.... statement?
I didn't see why you test #ifdef, too?

Additionally it would be nice, if you could integrate the i2c / pcie init in your patch?
Please see Simons patch at:
http://lists.infradead.org/pipermail/linux-arm-kernel/2009-October/001950.html

I have to leave now, but on monday I will do the test of your patch on my openrd-base board!

Many thanks,
Dieter
