A20-OLinuXino-MICRO Getting multiple SPI userspace busses

I just installed a fresh armbian 5.38 (mainline kernel) image to an SD Card for my A20-OLinuXino-MICRO board. After booting I used armbian-config to enable the spi-spidev. I then edited the armbianEnv.txt directly to add param_spidev_spi_bus=0.

 

This gives me a single spidev0.0 under dev. Changing the parameter to param_spidev_spi_bus=2 (or 1) I can get the other busses. But only a single bus at a time. I spent I few hours googling, but I cannot seem to find any documentation on how to enable more than one userspace spi dev.

 

Could someone explain to me how to enable all spi devices at once? Writing a custom overlays myself is a little beyond me at the moment.
