   4 Subject: [PATCH 2/6] MIPS: BCM47xx: Fill values for b43 into ssb sprom
   5
   6 Most of the values are stored in the nvram and not in the CFE. At first
   7 the nvram should be read and if there is no value it should look into
   8 the CFE. Now more values are read out because the b43 and b43legacy
   9 drivers needs them.
  10
  11 Some parts of this patch have been in OpenWRT for a long time and were
  12 made by Michael Buesch.
