PINE64 Rock64 - How to get SPI driver working

[Johannes Krottmayer]

Hi Kever,

I think you answered the wrong person. :)

Okay, thanks for the suggestions.

I will check the sources. There was also a missing alias
in the Device-Tree source. I have added the specific alias
for the SPI bus. Now I'm getting the error code -2.

I'm new with U-Boot and the source code itself, but I
think the problem occurs still in the device tree file for
the specific board.

Cheers,

Johannes K.
