+Subject: [PATCH] MIPS: BCM47xx: Add helper variable for storing NVRAM length
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+This simplifies code just a bit (also maybe makes it a bit more
+intuitive?) and will allow us to stop storing header. Right now we copy
+whole NVRAM including its header to the internal buffer. It is not
+needed to store a header as we don't access all these details like CRC,
+flags, etc. The next improvement that should follow is copying only the
+real contents.
