* This method is used to update firmware components such as CPLD,FPGA,BIOS,SMF
* This uses ONIE firmware upgrade design to stage firmware update from NOS.
a) Copy latest firmware updater image to target running sonic.
b) Run “./fw-updater -u onie-firmware-x86_64-dellemc_s5200_c3538-r0.3.40.5.1-9.bin”.
c) This would automatically reboot ONIE into update mode and update firmware components to latest and reboot back to sonic without any user intervention.
