From 1740c1bf40e3c6d03ac16c29943fdd9fc1e87038 Mon Sep 17 00:00:00 2001 From: Grant Erickson Date: Tue, 8 Jul 2008 08:35:00 -0700 Subject: ppc4xx: Add MII mode support to the EMAC RGMII Bridge This patch adds support for placing the RGMII bridge on the PPC405EX(r) into MII/GMII mode and allows a board-specific configuration to specify the bridge mode at compile-time.
