The NanoPi Neo2 is basically the same as the NanoPi Neo, but that they replaced the SoC with the 64-bit Allwinner H5 SoC. Add a (64-bit only) defconfig defining the required options to build the U-Boot proper.
Create a new .dts file for it by including the (32-bit) H3 SoC .dtsi and changing the differing components accordingly, like it's been done for the OrangePi PC 2.

I've tested this patch on top of yesterday's master branch (4c78028737c3185f49f5691183aeac3478b5f699 "mksunxi_fit_atf.sh: Allow for this to complete when bl31.bin is missing").
Considering Tom's unanswered question, is there any diff to the upstream kernel .dts? Expected would be to just copy the Linux .dts file here and to state which tree and commit/tag it was taken from.
I think we have a similar diversion between Linux and U-Boot .dts here, given that the U-Boot support was merged earlier. Updating the DTs for H5 and the board(s) was on my plan, but it's a bit more involved since it affects the H3 .dts as well (H3 and H5 use a shared stub .dtsi now). Also the H5 .dtsi just got into Linux (4.12-rc1), so it hasn't been in an officially released kernel yet.
Using this dtb here via UEFI distro boot, my openSUSE kernel image that booted okay on orangepi_pc2 fails to find the MMC devices on Neo2, although it obviously succeeded to boot from SD in U-Boot and GRUB...
Also, if I "reset" from the downstream or patched mainline U-Boot prompt, SPL gets stuck:

If instead I unpower it (by plugging Micro USB), it boots okay:

Your ATF build is quite old, it doesn't really support the H5. Please you the latest HEAD[1], it should print the SoC name at the beginning, and then won't try to configure an AXP on the H5. Please let me know if that fixes your problem.
Cheers, Andre.

Andre, is this reset problem maybe an ATF issue?
