+Subject: [PATCH] MIPS: BCM47XX: Use mtd as an alternative way/API to get NVRAM
+ content
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+NVRAM can be read using magic memory offset, but after all it's just a
+flash partition. On platforms where NVRAM isn't needed early we can get
+it using mtd subsystem.

-V2: I've noticed that Buffalo WZR-1750 uses an extra slash in NVRAM
- devpaths entries. I added support for them and updated comment.
- This adds one line over 80 chars, but it improved condition
- readability so I think it's alright there.
