That was my first guess as well, but: 
The aim is yet moving to powerpc not to break existing ppc/ stuff. 
So if alternatively platform_data may be utilized, all relevant ppc
stuff that uses cpm uart should be updated. While doing the driver
"platformize" trick, I made it possible to keep legacy behaviour
(pd-less), this is not going to afford such a thing. 

IOW, I don't see much sense in updating ppc/ BSP files, just to keep
the right way. It does not look very neat now, but does the job of
moving FW and keeping existing stuff sane. If there is better approach
envisioned, I'll definitely follow..
