From 292d4cf9257921912e8ea352687c977208e7553d Mon Sep 17 00:00:00 2001
From: Luka Perkov <luka@openwrt.org>
Date: Mon, 11 Nov 2013 07:27:53 +0100
Subject: [PATCH 2/9] kirkwood: define empty CONFIG_MVGBE_PORTS by default
Each board with defines it's own set of values. If we do not define
CONFIG_MVGBE_PORTS we will hit following error:
mvgbe.c: In function 'mvgbe_initialize':
mvgbe.c:700:34: error: 'CONFIG_MVGBE_PORTS' undeclared (first use in this function)
u8 used_ports[MAX_MVGBE_DEVS] = CONFIG_MVGBE_PORTS;
This patch fixes above described problem.
