Here is the set of command which has been performed to proof this feature.
gzip < fpga.bin > fpga.bin.gz mkimage -A arm -O u-boot -T firmware -C gzip \ -a 20000000 -n "zc702_fpga_bin" -d fpga.bin.gz fpga.bin.gz.ub
tftp 100000 fpga.bin.gz.ub fpga loadmk 0 100000
This flow should speedup loading bitstream data from external memory and save image footprint in non volatile memory.
