Hello Roger, These config options are required despite of they are
present in the file that is being included for buildman to work, you can
refer to Tom's comment at here:
https://lore.kernel.org/r/20240705153721.GF38804@bill-the-cat/
after which I included the same while posting config file for AM62x-SK.

Please explain in commit log why you are setting many of the
options to "n". Is it due to memory limitation?
Yes, that is because of memory limitation, we have faced the same
limitation while working with AM62x Ethernet boot.

Why no OF_UPSTREAM?
Device tree files are not in-sync with upstream linux for AM68, getting
compile time errors for the same, that's the reason I have disabled this
config option.
