microblaze doesn't have NUMA or dma_mapping_ops, afaict, so it should
just be

struct dev_archdata {
/* Optional pointer to an OF device node */
struct device_node *of_node;
};

These parameters are so common that they should become asm-generic/param.h.
4kb page size is of course a HW feature, but it's so universal that it's almost
a natural constant ;-)

please use the existing asm-generic/topology.h here.
