No, you don't pass it a phys_addr_t or a resource_size_t, you pass it a
struct resource *

Now, I would have liked to have a way to print a resource_size_t (or
phys_addr_t) but that's harder because we need pointers for the magic
typechecking to work (among others).

Maybe we could create a special format for a pointer-to-resource_size_t
and pass &foo on callers but that's fishy...
