Hi all,

I wanted to test the newly introduced kontron-sl-mx8mm_defconfig but
it does not work.

I already found two converted config options that are missing in that defconfig:

+CONFIG_SPL_MMC=y
+CONFIG_SPL_SERIAL=y

With that the output appears but the u-boot hangs when trying to find
the binman node in the dtb.

Does anyone have an idea what goes wrong?

I already disabled BINMAN_FDT an the u-boot start but when printing
the fdt node I do not see the binman node:
