From cae9008f69ab07b6faf75ebd0167ef06b8ebaf99 Mon Sep 17 00:00:00 2001 From: Stefan Roese Date: Sat, 25 Apr 2015 06:29:52 +0200 Subject: arm: mvebu: Change network init code to allow a more flexible setup With the introduction of the Armada 38x support, its necessary to change the mvneta ethernet driver init call from always 4 times to a configurable value. Lets make this init call more flexible by moving the actually used devices to the config header. Additionally this patch takes care of the slightly different base addresses for the ethernet controllers on A38x.
