+Subject: [PATCH] MIPS: BCM47xx: Move NVRAM header to the include/linux/.
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+There are two reasons for having this header in the common place:
+1) Simplifying drivers that read NVRAM entries. We will be able to
+   safely call bcm47xx_nvram_* functions without #ifdef-s.
+2) Getting NVRAM driver out of MIPS arch code. This is needed to support
+   BCM5301X arch which also requires this NVRAM driver. Patch for that
+   will follow once we get is reviewed.
