32BIT kernel don't compile, because you use TO_UNCAC which only

convert from physical to an uncached address. But I'd prefer if
you add resources to your platform device and do ioremap in device
drivers. This way there is also no need to export the interrupt
defines outside.
:( Jiaxun told me to use TO_UNCAC because CKSEG1 was unclear to him...
I will change back to CKSEG1. ioremap seems much needless overhead.
Sorry, ignored that you have 32-bit kernel as well.
