-Subject: [PATCH 08/26] bcm47xx: prepare to support different buses
-
-Prepare bcm47xx to support different System buses. Before adding
-support for bcma it should be possible to build bcm47xx without the
-need of ssb. With this patch bcm47xx does not directly contain a
-ssb_bus, but a union contain all the supported system buses. As a SoC
-just uses one system bus a union is a good choice.
