This is an Odroid-X2. I'm booting from SD with a Sandisk Extreme. I
don't have any eMMC here.

Actually it was some other person who encountered this issue with his
Odroid-X2 and booting from SD. After he made me aware of it, I also
updated my u-boot (I was then using a version from May 2015, which works
perfectly btw) and encountered the very same issue as him.

For me it restores proper operation of the bootloader to the board.
