From ce47eb402c5e29a025399dc282246414fc492940 Mon Sep 17 00:00:00 2001 From: Peter Tyser Date: Tue, 16 Sep 2008 10:04:47 -0500 Subject: [PATCH] Support for multiple SGMII/TBI interfaces for TSEC ethernet Fix TBI PHY accesses to use the proper offset in CPU register space. The previous code would incorrectly access the TBI PHY by reading/writing to CPU register space at the same location as would be used to access external PHYs.
