[devices]: Firmware upgrade support for DellEMC platforms(s5248,s5232…
…,z9100,s6100,z9264f) (#3743) * 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.
