-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.
