Firefly full OTA compilation and upgrade

Add the -o parameter for OTA full compilation

   ./FFTools/make.sh -d aio-3588sjd4 -j8 -l aio_3588sjd4-userdebug -o

Generate the full package path

   out/target/product/aio_3588sjd4/aio_3588sjd4-ota-eng.xxx.zip 

Generate the base material package path

   out/target/product/aio_3588sjd4/obj/PACKAGING/target_files_intermediates/aio_3588sjd4-target_files-eng.xxx.zip

Copy the base material package and rename it, mainly for
subcontracting upgrades.

   cp out/target/product/aio_3588sjd4/obj/PACKAGING/target_files_intermediates/aio_3588sjd4-target_files-eng.xxx.zip ~/ota/v1.zip 

Package compiled firmware and upgrades

   ./FFTools/mkupdate/mkupdate.sh -l aio_3588sjd4-userdebug

In the "rockdev/Image-aio_3588sjd4/" directory, find the corresponding
firmware and burn it to the machine, then the machine can carry out
the full package upgrade and the difference package upgrade,put
'update.zip' into /sdcard/ and restart the full package as prompted.

Generate the incremental OTA package

Generate a new base material package

The v1.zip basic material package has been made, and another v2.zip
material package needs to be made to generate the difference package.
You need to modify the kernel DTS code or Android code, and then run
the command again.

   ./FFTools/make.sh -d aio-3588sjd4 -j8 -l aio_3588sjd4-userdebug -o

Regenerate a new base material package that we can copy.

    cp out/target/product/aio_3588sjd4/obj/PACKAGING/target_files_intermediates/aio_3588sjd4-target_files-eng.xxx.zip  ~/ota/v2.zip

Generate the incremental OTA package command

   out/host/linux-x86/bin/ota_from_target_files --block -v -i ~/ota/v1.zip -p out/host/linux-x86/ -k build/target/product/security/testkey ~/ota/v2.zip update.zip
