Download the bootloader binaries

+1, I was used to download UEFI image files from but it looks like the directory disappeared. By any chance, does someone have an idea where they have been moved? I tried several fip.bin/l-loader.bin from other directories, unsuccessfully.
My goal is to put Debian on the Hikey960 board.

Thank you in advance!

Kind regards
