I'd suggest this docs update to be taken, as the combination of ATF and DDR firmware
recorded there is known to be working for those i.MX8M derivatives.

I've also realized that there is a newer version of ATF available from NXP on codeaurora,
but according to the last mail from Fabio - it is not bootable, and I haven't tried it
myself yet.

I guess for the upcoming 2021.01 this documentation update would be quite helpful,
as there has been few reports on the list that people tried to use outdated instructions
and were not able to produce a boot container for i.MX8M Nano and Plus SOCs due to
a newer version of ATF was required.
