From cc025e749a1fece61a6cc0d64bbe7b12472259cc Mon Sep 17 00:00:00 2001
From: Jonas Gorski <jogo@openwrt.org>
Date: Tue, 29 Jul 2014 21:31:12 +0200
Subject: [PATCH 01/10] MIPS: BCM63XX: move fallback sprom support into its own
unit
In preparation for enhancing it, move it into its own file. Require a
mac address to be passed as the argument to always "reserve" the mac
regardless of the inclusion state of SSB.
Signed-off-by: Jonas Gorski <jogo@openwrt.org>
