Yes, there are.  But your console port cannot be compred against
dynamically populated and scannable bus interfaces like USB or PCI,
and I think you are aware of that.

Not any dynamic device registration.  But here, it actually AIN'T
dynamic - it is fully static, just board dependent.

No.

NAK.  This is totally wrong.  ODMDATA is just a different
representation of information that could as well be encoded in a DT.
PCI or USB bus scanning gives information which cannot be encoded in a
DT passed to U-Boot (at least not unless you dynamically generate that
DT using some other softeware performing such a bus scan).
