Clone https://github.com/LibreELEC/amlogic-boot-fip, and put the data files (e.g. ordroid-n2/* or odroid-n2-plus/*) into the data-files folder.

Clone https://gitlab.denx.de/u-boot/custodians/u-boot-amlogic.git to build the amlogic u-boot.bin

git clone https://gitlab.denx.de/u-boot/custodians/u-boot-amlogic.git
nix-shell -p '[ pkgsCross.aarch64-multiplatform.buildPackages.binutils pkgsCross.aarch64-multiplatform.stdenv.cc bison yacc flex bc ]'
make CROSS_COMPILE=aarch64-unknown-linux-gnu- odroid-n2_defconfig
make CROSS_COMPILE=aarch64-unknown-linux-gnu-

(See also ./doc/board/amlogic/odroid-n2.rst in u-boot-amlogic).

The u-boot.bin will be the bl33.bin (see above!).
