I am doing platform development for an sdm710 board and the flash_all.sh script requires many files that I could not find in the /out folder or anywhere in my AOSP build.

Those files include for example xbl.elf, qupv3fw.elf, cmnlib.mbn or tz.mbn. Are those files usually provided by the manufacturer as binaries?
Or should they be generated when building Android?

I would like to flash them with fastboot but cannot find them.

thank you for any help!
