3) Add device tree source for Wind River SBC8560 board

This is probably the most interesting part of the group, given that  
the
board doesn't use the CPM2 to provide the serial console.  I've made a
duart dts entry that is kind of similar to what is done for the tsi108
on the mpc7448/hpc-ii board, and made sure that the serial had their
parent marked as "soc" (found out the hard way that UARTs were ignored
as possible consoles unless they were soc or tsi108 children...)

we need to figure out to fix this so we don't need the parent marked  
as 'soc'.

Out of interest how exactly are the duart's wired on the 8560.  Are  
they off localbus?

I'd quickly spun together a u-boot 1.2.0 for testing this -- since  
that was
the quickest route to getting a powerpc capable version.  I'll see  
what
can be done for getting a u-boot 1.3.1 patchset out so the local-mac- 
address
vs address thing in the dtb isn't an issue.


Probably should add a boot wrapper to work with old non-device tree  
aware u-boots.
