Subject: [PATCH 1/6] MIPS: BCM47xx: Do not read config from CFE
The config options read out here are not stored in CFE, but only in
NVRAM on the devices. Remove reading from CFE and only access the NVRAM.
Reading out CFE does not harm, but is useless here.

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.
Fill the sprom with all available values from the nvram. Most of these
new values are needed for the b43 or b43legacy driver.
Some parts of this patch have been in OpenWRT for a long time and were
made by Michael Buesch.

Subject: [PATCH 5/6] b44: fix workarround for wap54g10
The code for the b44_wap54g10_workaround was never included, because
the config option was wrong. The nvram_get function was never in
mainline kernel, only in external OpenWrt patches.
The code should be compiled in when CONFIG_BCM47XX is selected and not
when CONFIG_SSB_DRIVER_MIPS is selected, because nvram_getenv is only
available on bcm47xx platforms and now in the mainline kernel code.
Using an include is better than a second function declaration, to fix
this when the function signature changes.

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