From 063c12633d5ad74d52152d9c358e715475e17629 Mon Sep 17 00:00:00 2001 From: Andy Fleming Date: Fri, 8 Apr 2011 02:10:54 -0500 Subject: [PATCH] tsec: Convert tsec to use PHY Lib This converts tsec to use the new PHY Lib. All of the old PHY support is ripped out. The old MDIO driver is split off, and placed in fsl_mdio.c. The initialization is modified to initialize the MDIO driver as well. The powerpc config file is modified to configure PHYLIB if TSEC_ENET is configured.
