replace it with "Burning" or "Flashing"? which document how we burn the

the procedure above is too complicated and obscure.. I would suggest to use fastboot,
here is what I've tested on milkv jupitor board which burn the fw to spi nor flash,
it can be flashed to emmc/sd card, and should be smiliar on BPI F3 board.

collect FSBL.bin, u-boot.itb,  partition_2M.json, bootinfo_spinor.bin
u-boot-env-default.bin, fw_dynamic.itb from vendor sdk

fastboot stage FSBL.bin
fastboot continue
fastboot stage u-boot.itb-vendor # the itb from vendor uboot
fastboot continue

fastboot flash mtd partition_2M.json
fastboot flash bootinfo bootinfo_spinor.bin
fastboot flash fsbl FSBL.bin
fastboot flash env u-boot-env-default.bin
fastboot flash opensbi fw_dynamic.itb

fastboot flash uboot u-boot.itb-mainline # the itb from mainline uboot
