After the conversion 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 binary because the extra u-boot.itb is now required.
Generate a final flash.bin that can be used again as a single bootable binary to keep the original behavior.
After this change the SPL binary is called spl.bin, which is a more descriptive name for its purpose, and can still be used standalone (for example, for secure boot purposes).

I tried to adapt this for my own board, but I needed to change the following in the imximage.cfg for the build to pass. Did you test this?
-LOADER mkimage.flash.mkimage 0x7E1000 +LOADER mkimage.spl.mkimage 0x7E1000
Best regards Frieder
