Details

nvramUpdate updates the nvram in Broadcom models from a (ASCII or binary) file. It is not used by the system.
The binaries are SoC specific and typically located in /etc/wlan, see the Examples below.

7581 fw 7.17: 

root@fritz:/var/mod/root# nvramUpdate -h

Usage: 

nvramUpdate [-m] [-s tftpdserver] [-h] {DataFileName | Recover | Read | Show | Clean | Feature} 

==============================
-m:       Option -m for {Clean} and {Data} indicate manufacture automation to bypass prompt
-s:       Option -s tftpdserver where nvram map binary file are loaded from
-d:       Option -d to specify where the nvram map binary to put on system, default to /etc/wlan
-h:       Option -h for help
==============================

Clean:    Clean up Nvram
Read:     Read back Calibration data in binary format
Show:     Read back Calibration data in input ASCII file format
Recover:  Copy all nvramMap .bin from backup to /etc/wlan 
Feature:  Get/Set wl feature settings
DataFileName: Nvram data file name,when ended with ".bin",it indicates as a complete nvram MAP
              it will be loaded to /etc/wlan or the directory where -d is given, if file name is
              not ended with ".bin",it will be partial change and formated as:

    ###################
    ID=pci/bus/slot/ Or
    ID=pci/domain/bus/slot/
    offset1=value1
    ......
    ID=pci/bus/slot/
    offset1=value1
    ......
    offsetn=valuen
    ###################

    Example: 52=38fc 
    value is 16bit hexical data
    Offset is decimal, 16bit aligment offset(not 8bit alignment offset)
    The ID will print in console when driver load
