pxa-dt and multiple platforms support

[Robert Jarzmik]

Hi Daniel,

When you added support for device-tree for pxa3xx, in commit "ARM: pxa3xx: add
generic DT machine code" (e7749a2) you wrote : "This file can be extended to
also support pxa2xx".

I was wondering is that is really possible with the current pxa status, because
:
 - you have to include mach/pxa3xx.h
   => this includes mach/pxa3xx-regs.h
   => this is specific to pxa3xx architecture

If I add pxa27x support into the same file, I'll have to include mach/pxa27x.h
(because the initialization functions are there, same reason as yours for
mach/pxa3xx-regs.h).
   => this includes mach/pxa2xx-regs.h
   => this is specific to pxa2xx architecture

Of course there will be a lot of defines conflicts, as both platforms share the
same register names ...

So did you have something specific in mind, or should I rename pxa-dt.c into
pxa3xx-dt.c, and create pxa27-dt.c (this last option is my current choice unless
a better ideas emerges) ?

Cheers.
