Your lines are way too long. Please restrict your line length to some
70 characters or so.

Some 130 KiB are pretty normal (and actually even small) for a
current version of U-Boot.

Undefine features you don't need to get any significant savings,  and
use a more recent tool chain version to get the last few percent.

Best regards,

You can do this in a number of ways.     IBM chose to do all of them.
