From 9912a8b3c240a9b0af01ff496b7e8ed9e4cc5b82 Mon Sep 17 00:00:00 2001
From: Jonas Gorski <jogo@openwrt.org>
Date: Tue, 29 Jul 2014 21:43:49 +0200
Subject: [PATCH 02/10] MIPS: BCM63XX: use platform data for the sprom
Similar to ethernet setup, use a platform data struct for passing
the mac. This eliminates the requirement to allocate an array on
stack for the mac passed.
