From ca08054e80c64402f6a767a6a188dcfc096eb3b9 Mon Sep 17 00:00:00 2001 From: Stefan Roese Date: Tue, 29 Jun 2010 09:23:53 +0200 Subject: [PATCH] net: Add option to disable fiber on M88E1111 PHY for PPC4xx By defining CONFIG_M88E1111_DISABLE_FIBER boards can configure the M88E1111 PYH to disable fiber. This is needed for an upcoming PPC460GT based board, which has fiber/copper auto-selection enabled by default. This doesn't seem to work. So we disable fiber in the PHY register.
