-Subject: [PATCH 09/17] bcma: store more alternative addresses
-
-Each core could have more than one alternative address. There are cores
-with 8 alternative addresses for different functions. The PHY control
-in the Chip common B core is done through the 2. alternative address
-and not the first one.
