From dd35479a50f6c7c31ea491c07c5200c6dfd06a24 Mon Sep 17 00:00:00 2001 From: Ben Warren Date: Mon, 23 Jun 2008 22:57:27 -0700 Subject: Add mechanisms for CPU and board-specific Ethernet initialization This patch is the first step in cleaning up net/eth.c, by moving Ethernet initialization to CPU or board-specific code. Initial implementation is only on the Freescale TSEC controller, but others will be added soon.
