Hi Tom,
Please have a look at the below patches. Travis-ci can be found here: https://travis-ci.org/mbgg/u-boot/builds/614078145
Apart from this patches, I planning to send another pull request once the single binary series is ready to be merged. But for now, we should take this patches as it fixes some FAT write errors and the boot banner issue for RPi3 you detected.
Regards, Matthias
