Linux Kernel Configuration
└─>Firmware Drivers
└─>Broadcom SPROM driver
In linux kernel since version 3.10 (release Date: 2013-06-30)  
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.
