Subject: [PATCH 10/15] 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.
