└─>Broadcom NVRAM driver
In linux kernel since version 3.10 (release Date: 2013-06-30)  
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.
