Now that the DT core code handles bootmem arches, we can remove the metag specific early_init_dt_alloc_memory_arch function. As the default early_init_dt_add_memory_arch just does a WARN, we can remove it too. Cc: James Hogan <jhogan@kernel.org> Cc: linux-metag@vger.kernel.org Signed-off-by: Rob Herring <robh@kernel.org>
