will do it on next submission

> This might be due to the fact that you're using the same u-boot-nodtb.bin binary twice: once in binman section, and once in ITB. You can try to rename the binman entry to a different name, this might do the trick. See [1] for sample of imx8mq_evk conversion.
 
ok I think I fixed that. I dropped additionally the following
statements:

make u-boot.bin
make flash.bin 

just make is enough here or?

But still get this warning even if CONFIG_SPL_FIT_GENERATOR is disabled.

make imx8qm_rom7720_a1_4G_defconfig && make
#
# configuration written to .config
#
scripts/kconfig/conf  --syncconfig Kconfig
  CFG     u-boot.cfg
  GEN     include/autoconf.mk
  GEN     include/autoconf.mk.dep
  CFG     spl/u-boot.cfg
  GEN     spl/include/autoconf.mk
===================== WARNING ======================
This board uses CONFIG_SPL_FIT_GENERATOR. Please migrate
to binman instead, to avoid the proliferation of
arch-specific scripts with no tests.

You find the doc here:

you are right. This is still missing. Can you point me to a example with
SECO and SCFW?
