-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.
