After the convesion to binman in commit 8996e6b7c6a1 ("imx8mm_evk: switch to use binman to pack images"), it is necessary to flash both flash.bin and u-boot.itb to get a bootable system. Prior to this commit, only flash.bin was needed.
Such new requirement breaks existing distro mechanisms to generate the final image because the extra u-boot.itb is now required.
Generate a final flash.bin image that can be used again as a single bootable image to keep the original behavior.

imx-boot {filename = "flash.bin";I am unsure here, if it makes sense to overwrite flash.bin with the binary which contains SPL and u-boot.itb. May others want to use them (as I currently use them for signing them)
Why not imx-boot as image name as in NXP sources? (Thats why I named it so in my "fast example approach")
Is it right that in that case a new u-boot makefile target has to be set? Currently flash.bin works because it is already set in "arch/arm/mach-imx/Makefile"?
No, I think not, that is binman magic ... binman creates the targets which are defined in your DTS in the binman node, see:
u-boot:/tools/binman/README.rst
