bgmac: add supprot for BCM4707
From 2e3759f95d3c96282c19e6f57274d816c6cf1a0e Mon Sep 17 00:00:00 2001

Subject: [PATCH 4/5] bgmac: reset all cores on Northstar SoC
On the Northstar SoC (BCM4707 and BCM53018) we have to enable all GMAC
cores when we just want to use on. We iterate over all the cores and
activate them.
Subject: [PATCH 5/5] bgmac: add support for Northstar SoC (BCM4707, BCM53018)
This adds support for the Northstar SoC. This SoC does not have a PMU in
bcma and no register on it should be called. In addition it support 2.5
GBit/s Ethernet to the PHY.
This GMAC core is not fully working there are still problems with the
DMA controller.
