   4 Subject: [PATCH 2/6] MIPS: BCM47xx: Fill values for b43 into ssb sprom
   5
   6 Fill the sprom with all available values from the nvram. Most of these
   7 new values are needed for the b43 or b43legacy driver.
   8
   9 Some parts of this patch have been in OpenWRT for a long time and were
  10 made by Michael Buesch.
