This driver provides an easy way to get value of requested parameter.
It simply reads content of NVRAM and parses it. It doesn't control any
hardware part itself.
+
+config BCM47XX_SPROM
+ bool "Broadcom SPROM driver"
+ depends on BCM47XX_NVRAM
+ help
+ Broadcom devices store configuration data in SPROM. Accessing it is
+ specific to the bus host type, e.g. PCI(e) devices have it mapped in
+ a PCI BAR.
+ In case of SoC devices SPROM content is stored on a flash used by
+ bootloader firmware CFE. This driver provides method to ssb and bcma
+ drivers to read SPROM on SoC.

-Subject: [PATCH 03/17] bcm47xx-sprom: add Broadcom sprom parser driver
-
-This driver needs an nvram driver and fetches the sprom values from the
-nvram and provides it to any other driver. The calibration data for the
-wifi chip the mac address and some more board description data is
-stores in the sprom.
-
-This is based on a copy of arch/mips/bcm47xx/sprom.c and my plan is to
-make the bcm47xx MIPS SoCs also use this driver some time later.
