 The previews patch 84a6fcb368a080620d12fc4d79e07902dbee7335 was wrong,
 I got wrong success reports.

+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.

+Change nvram_getenv to do the same.

+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.

+nvram_getenv should behave like cfe_getenv. For now it is used like

+Change nvram_getenv to do the same.
