+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.
