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"; -+ reg = <0x1c000000 0x01000000>; -+}; ---- a/drivers/misc/Kconfig -+++ b/drivers/misc/Kconfig -@@ -515,6 +515,11 @@ config VEXPRESS_SYSCFG - bus.
