[PATCH] PowerPC: Add RGMII support for Sequoia 440EPx

From: Valentine Barshak <hidden>
Date: 2007-10-01 14:13:20

This adds RGMII support to Sequoia DTS and sets correct phy-mode
for EMACs. According to Sequoia datasheet, both ethernet ports
are connected to RGMII interface, while ZMII is used only for MDIO.

I'm going to hold off on this one until the new EMAC driver is in Paul's
tree.
