[U-Boot] [GIT PULL] Raspberry Pi updates for v2020.01

[Matthias Brugger]

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
