Details
libnvram.so is the backend for persistent storage of configuration on Broadcom chipsets. similar to what TFFS does.
It is a proprietary blackbox and the exact location of the data differs and has yet to be researched.
On a 7581 fw 7.17 this lib is a wrapper of the wlcsm_nvram_* functions of libwlcsm.so, which uses the nvram (partition).
On a 7530 additionally the proprietary kernel backend enabled by CONFIG_BCM_NVRAM is used. It is supported by
the common_nvram_kernel_* and nvram_k* functions of this lib, see the Symbols below.
libnvram.so is used by many Broadcom executables. There's also the commandline frontend nvram (chipcmd).
