-Subject: [PATCH] MIPS: BCM63XX: move nvram functions into their own file
-
-Refactor nvram related functions into its own unit for easier expansion
-and exposure of the values to other drivers.
-
-Signed-off-by: Jonas Gorski <jonas.gorski@gmail.com>

-This patch depends on the previous reset helper patch series or the
-Makefile change needs to be merged manually. It has no real functional
-dependencies.
