Broadcom ARM home routers store SPROM content in NVRAM just like MIPS ones. To share SPROM code we need to move it out of arch/mips/ to some common place. We already have bcm47xx_nvram in firmware path and SPROM should fit there as well. This driver is responsible for parsing SoC configuration data into a struct shared between ssb and bcma buses. This was tested with BCM4706 & BCM5357C0 (BCM47XX) and BCM4708A0 (ARCH_BCM_5301X).

Broadcom home routers contain flash partition called "nvram" with all
|
|
important hardware configuration as well as some minor user setup.
|
|
NVRAM partition contains a text-like data representing name=value
|
|
pairs.
|
|
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.
