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. + +Signed-off-by: Hauke Mehrtens <hauke@hauke-m.de> +--- + .../devicetree/bindings/misc/bcm47xx-nvram.txt | 19 ++ + arch/mips/bcm47xx/board.c | 40 ++-- + arch/mips/bcm47xx/nvram.c | 7 +- + arch/mips/bcm47xx/setup.c | 4 +- + arch/mips/bcm47xx/sprom.c | 4 +- + arch/mips/bcm47xx/time.c | 2 +- + drivers/misc/Kconfig | 5 + + drivers/misc/Makefile | 1 + + drivers/misc/bcm47xx-nvram.c | 215 +++++++++++++++++++++ + drivers/net/ethernet/broadcom/b44.c | 2 +- + drivers/net/ethernet/broadcom/bgmac.c | 5 +- + drivers/ssb/driver_chipcommon_pmu.c | 3 +- + include/linux/bcm47xx_nvram.h | 17 +- + 13 files changed, 286 insertions(+), 38 deletions(-) + create mode 100644 Documentation/devicetree/bindings/misc/bcm47xx-nvram.txt + create mode 100644 drivers/misc/bcm47xx-nvram.c + +--- /dev/null ++++ b/Documentation/devicetree/bindings/misc/bcm47xx-nvram.txt +@@ -0,0 +1,19 @@ ++Broadcom bcm47xx/bcm53xx nvram access driver ++ ++This driver provides access to the nvram for other drivers. ++ ++Required properties: ++ ++- compatible : brcm,bcm47xx-nvram ++ ++- reg : iomem address range ++ ++On NorthStar ARM SoCs the NAND flash is available at 0x1c000000 and the ++NOR flash is at 0x1e000000 ++ ++Example: ++ ++nvram0: nvram@0 { ++ compatible = "brcm,bcm47xx-nvram";
