If you only made a few changes like config the easiest way may be just to patch inside a bbappend.

If there are changes in the u-boot itself it may worth to run an own u-boot git and sync it with denx or TI.

It's basically creating a new board configure section so it should boil down to 5 or six new files and one edit to boards.cfg.

You can overwrite the SRC_URI in the bbappend as-well.

So I tried this and it didn't seem to work. I would also have to override the SRCREV, maybe it was that that didn't work. I can try again.

I am a bbappend fan boy so I would prefer this over an new recipe.

But it may worth to look at the various layers like freescale and TI how they solved this.

It doesn't look like TI uses bbappends here, I'll have to look at Freescale.
