+commit 121915c4ee0812a14bc8d752bc210d0238d755c1
+Author: Waldemar Brodkorb <mips@waldemar-brodkorb.de>
+Date:   Tue Jun 8 19:06:01 2010 +0200
+
+    MIPS: BCM47xx: Add NVRAM support devices
+    
+    When trying to netboot a Linksys WRT54GS WLAN router, the bootup fails,
+    because of following error message:
+    
+    ...
+    [    0.424000] b44: b44.c:v2.0
+    [    0.424000] b44: Invalid MAC address found in EEPROM
+    [    0.432000] b44 ssb0:1: Problem fetching invariants of chip,aborting
+    [    0.436000] b44: probe of ssb0:1 failed with error -22
+    ...
+    
+    The router uses a CFE bootloader, but most of the needed environment
+    variables for network card initialization, are not available from CFE
+    via printenv and even though not via cfe_getenv().
+    The required environment variables are saved in a special partition
+    in flash memory. The attached patch implement nvram_getenv and enables
+    bootup via NFS root on my router.
+    
+    Most of the patch is extracted from the OpenWrt subversion repository and
+    stripped down and cleaned up to just fix this issue.
+    
+    [Ralf: sorted out header file inclusions.  Lots of unneded headers and such
+    that should have been included.]

+Subject: [PATCH 1/5] MIPS: BCM47xx: Really fix 128MB RAM problem
+
+The previews patch 84a6fcb368a080620d12fc4d79e07902dbee7335 was wrong,
+I got wrong success reports.
+
+The bcm47xx architecture maps the ram into a 128MB address space. It
+will be paced there as often as goes into the 128MB. The detection
+tries to find the position where the same memory is found. When reading
+over 128MB the processor will throw an exception. If 128MB ram is
+installed, it will not find the same memory because it tries to read
+over the 128MB boarder. Now it just assumes 128MB installed ram if it
+can not find that the ram is repeating.

+Subject: [PATCH 2/5] MIPS: BCM47xx: Fill more values 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.

+Subject: [PATCH 1/5] MIPS: BCM47xx: Really fix 128MB RAM problem
+
+The previews patch 84a6fcb368a080620d12fc4d79e07902dbee7335 was wrong,
+I got wrong success reports.
+
+The bcm47xx architecture maps the ram into a 128MB address space. It
+will be paced there as often as goes into the 128MB. The detection
+tries to find the position where the same memory is found. When reading
+over 128MB the processor will throw an exception. If 128MB ram is
+installed, it will not find the same memory because it tries to read
+over the 128MB boarder. Now it just assumes 128MB installed ram if it
+can not find that the ram is repeating.

+Subject: [PATCH 2/5] MIPS: BCM47xx: Fill more values 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.
