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.

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.
