+Subject: [PATCH 155/158] MIPS: BCM47XX: Make ssb init NVRAM instead of bcm47xx
+ polling it
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+This makes NVRAM code less bcm47xx/ssb specific allowing it to become a
+standalone driver in the future. A similar patch for bcma will follow
+when it's ready.

+Subject: [PATCH 157/158] MIPS: BCM47XX: Move SPROM fallback code into sprom.c
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+This is some general cleanup as well as preparing sprom.c to become a
+standalone driver. We will need this for bcm53xx ARM arch support.

+Subject: [PATCH 155/158] MIPS: BCM47XX: Make ssb init NVRAM instead of bcm47xx
+ polling it
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+This makes NVRAM code less bcm47xx/ssb specific allowing it to become a
+standalone driver in the future. A similar patch for bcma will follow
+when it's ready.

+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+Initializaion with memory allocator available will be much simpler, this
+will allow cleanup in the bcma code.
