+From f6a95a24957aec5bb488c3f978c4ed508177998f Mon Sep 17 00:00:00 2001
+From: Jon Mason <jon.mason@broadcom.com>
+Date: Thu, 7 Jul 2016 19:08:57 -0400
+Subject: [PATCH 5/5] net: ethernet: bgmac: Add platform device support
+
+The bcma portion of the driver has been split off into a bcma specific
+driver. This has been mirrored for the platform driver. The last
+references to the bcma core struct have been changed into a generic
+function call. These function calls are wrappers to either the original
+bcma code or new platform functions that access the same areas via MMIO.
+This necessitated adding function pointers for both platform and bcma to
+hide which backend is being used from the generic bgmac code.
