From 41410eee472b0f42e03a77f961bbc55ef58f3c01 Mon Sep 17 00:00:00 2001 From: Haiying Wang Date: Wed, 24 Sep 2008 11:42:12 -0500 Subject: Change UEC PHY interface to RGMII on MPC8568MDS Change UEC phy interface from GMII to RGMII on MPC8568MDS board Because on MPC8568MDS, GMII interface is only recommended for 1000Mbps speed, but RGMII interface can work at 10/100/1000Mbps, and RGMII interface works more stable. Now both UEC1 and UEC2 can work properly under u-boot. It is also in consistent with the kernel setting for 8568 UEC phy interface.
