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.

Subject: [PATCH 10/17] bcma: add support for chipcommon B core
This core is used on BCM4708 to configure the PCIe and USB3 PHYs and it
contains the addresses to the Device Management unit. This will be used
by the PCIe driver first.
