   4 Subject: [PATCH 6/6] sb: fix nvram_get on bcm47xx platform
   5
   6 The nvram_get function was never in the mainline kernel, it only
   7 existed in an external OpenWrt patch. Use nvram_getenv function, which
   8 is in mainline and use an include instead of an extra function
   9 declaration.
  10 et0macaddr contains the mac address in text from like
  11 00:11:22:33:44:55. We have to parse it before adding it into macaddr.
  12
  13 nvram_parse_macaddr will be merged into asm/mach-bcm47xx/nvram.h though
  14 the MIPS git tree and will be available soon. It will not build now
  15 without nvram_parse_macaddr, but it haven't done before.
