Subject: [PATCH 2/6] MIPS: BCM47xx: Fill values for b43 into ssb sprom
|
|
|
|
Most of the values are stored in the nvram and not in the CFE. At first
|
|
the nvram should be read and if there is no value it should look into
|
|
the CFE. Now more values are read out because the b43 and b43legacy
|
|
drivers needs them.
|
|
|
|
Some parts of this patch have been in OpenWRT for a long time and were
|
|
made by Michael Buesch.
