In the vendor's U-Boot SPL, OpenSBI and U-Boot are loaded separately. From my observation, U-Boot seems to prefer loading a FIT image that includes both OpenSBI and U-Boot. Therefore, I modified this part to allow them to be loaded together. The modified code might be somewhat messy because I just made it work. As a result, it is currently difficult to describe how to boot into U-Boot. Perhaps I can improve the documentation after U-Boot SPL is available for Banana Pi F3.
