Hi Florian

This is not going to work with John's rework of my multi CPU ports
code. I think you are going to have to modify the platform_data
structure to support multi-CPU ports.

I put higher priority on cleanly integrating multi-CPU ports using
device tree, than supporting legacy platforms. I'm O.K. with
preparatory patches, but i think we should wait for actually platform
data changes until after Johns code has landed and we can design the
platform_data to work with it.
