What is the plan to convert this board to OF_UPSTREAM?

Has the DTS already been submitted upstream? Please include the lore
link of the submission.

There is no need for this IMX91_FRDM_LPDDR4 symbol. Please drop it.

It would make sense if there was a DDR4 version too.

Why do we need two defconfigs for this board?

What are the pros and cons of using one versus the other?

Can't we simply use a single one?

If you really need both, then please avoid duplication by adding
including a common include to both.
