From feede8b07013b33fca8dd2a916b3ac86bf4d4c0a Mon Sep 17 00:00:00 2001 From: Andy Fleming Date: Fri, 5 Dec 2008 20:10:22 -0600 Subject: Fixup SGMII PHY ids in the device tree The device tree's PHY addresses need to be fixed up if we're using the SGMII Riser Card. The 8572, 8536, and 8544 DS boards were modified to call this function.
