The at91rm9200 emac seems to be a older version of the current (E)MAC(B) implementations. Some registers not available there, some flags have other places ... but maybe this could be done with the same driver. I just wonder why the linux kernel also have an at91-ether and dedicated macb driver? best regards Andreas Bießmann _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot
