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

From: Valentine Barshak <[email-masked]>
Date: Mon, 1 Oct 2007 18:12:09 +0400

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.
