Yes, I guess somebody should.

However, for now, I guess those should just go into the U-Boot specific include file as well.

Okay, I will add them to the U-Boot specific include file for now. Will send a v4 with that shortly.

Sure, much appreciated.

> Have you tested this change too with the board?

No, but supposedly Jesse did. However, it was not fully clear to me whether such further changes may be

Thanks!
