+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.
