Paul Burton ae07d609e9 powerpc: Use asm-generic/io.h ... Convert the powerpc architecture to make use of the new asm-generic/io.h to provide address mapping functions. As powerpc can actually perform non-identity mapping between physical & virtual addresses we can't simply make use of the generic phys_to_virt() & virt_to_phys() functions. However since map_physmem() already effectively implemented the same thing as virt_to_phys() we can simply implement virt_to_phys() instead of map_physmem() & use the generic map_physmem(). We also drop the no-op unmap_physmem(). This has only been build-tested, feedback from architecture maintainers is welcome.
