It correctly boots up to a U-boot prompt on my Rock64. However it
fails to read data correctly from the SD card afterwards:

booti ${kernel_addr_r} - ${fdt_addr_r}

=============

If I manually load the kernel Image, that also fails.
If I manually load the fdt file, it completes, but the data is
complete gibberish.
ls works fine though.

And removing the fifo-mode flag from
arch/arm/dts/rk3328-rock64-u-boot.dtsi makes it
not boot at all.

Previously I was using an old build from Armbian, and that worked fine.
