From 748031f9fd2c06b28817d80761a5de97190cfd03 Mon Sep 17 00:00:00 2001 From: Magnus Damm Date: Fri, 9 Oct 2009 00:17:14 +0000 Subject: [PATCH] net: allow sh_eth to get mac address through platform data Extend the sh_eth driver to allow passing the mac address using the platform data structure. This to simplify board setup code. Signed-off-by: Magnus Damm Tested-by: Kuninori Morimoto Signed-off-by: David S.
