Yes, we don't need ATAGs for the i.MX family as we use devicetree for
all i.MX members.

but reading serial identification via fuses is still supported and I
am not sure why this gets removed.

I am confused with this patch, as I don't understand the relationship
between ATAG and CONFIG_SERIAL_TAG.

You can assume that all i.MX devices boot only via DT.
