PINE64 Rock64 - How to get SPI driver working

I just compiled U-Boot v2020.04 for a PINE64 Rock media board.
It compiles fine without errors, but when I try to probe the
on board flash I get an error:
=> sf probe
Invalid bus 0 (err=-19)
Failed to initialize SPI flash at 0:0 (error -19)
SPI is activated in the Device-Tree blob. I also added support
to the Rockchip SPI driver (added IDS strings for this SoC).
In the device config I added the following:
But the driver still doesn't work. Output of DM (shortened):
=> dm tree
spi 0 [ ] rockchip_spi |-- spi at ff190000
spi_flash 0 [ ] spi_flash_std | `-- spiflash at 0
What is missing? Is there a way to load driver?
Any kind of help is highly appreciated.
