From d8d21e699d7fcfb6ab11635110266dd09b7edc62 Mon Sep 17 00:00:00 2001 From: Mike Frysinger Date: Mon, 16 Feb 2009 18:03:14 -0500 Subject: boards: move board_get_enetaddr() into board-specific init The environment is the canonical storage location of the mac address, so we're killing off the global data location and moving everything to querying the env directly. Rather than have the common ppc code have board-specific hooks, move the board_get_enetaddr() function into the board-specific init functions.
