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.

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.
