-Subject: [PATCH 01/17] MIPS: BCM47XX: move the nvram header file into common
- space
-
-Moving mach-bcm47xx/bcm47xx_nvram.h to include/linux/bcm47xx_nvram.h
-makes it possible to reuse this header on the ARM based bcm47xx/bcm53xx
-SoCs (e.g. BCM5301X devices). Broadcom uses ARM CPUs in their new SoC
-form the bcm47xx and bcm53xx line, but many other things like nvram
-stayed the same.
-
-This is a preparation for adding a new nvram driver, which can be used
-by the ARM SoC and the MIPS SoC code. The device drivers accessing
-nvram do not have to care about ARM or MIPS SoC version.

-Subject: [PATCH 02/17] bcm47xx-nvram: add new broadcom nvram driver with dt
- support
-
-This adds a new driver which searches at a given memory range for a
-nvram like it is used on the bcm47xx and bcm53xx SoCs with ARM and MIPS
-CPUs. This driver provides acces to this nvram to other device in the
-device tree. You have to specify the memory ranges where the content of
-the flash chip is memory mapped and this driver will search there for
-some nvram and parse it. Other drivers can use this driver to access the
-device nvram. The nvram is used to store board configurations like the
-mac addresses, the switch configuration and the calibration data for
-the wifi devices.
-
-This was copied from arch/mips/bcm47xx/nvram.c and modified to interact
-with device tree. My plan is to make the MIPS bcm47xx also use this new
-driver some time later.
