Correction: With Peng's current Binman patchset you need both. But I
think that is not correct, because for i.MX8MM Binman was changed back
to generate a single image. The following patch includes that change,
so you only need to dd flash.bin.

I have fixed the issue. My changes depend on Peng's patchset to change
i.MX8MQ to Binman, so I will re-issue a v3 of the patchset as soon as
that is done (to not interfere any further with his patchset).
'Attached' you'll find a complete diff you can apply to origin/master,
which includes some of Peng's changes. Let me know how it goes for you.
