Why not using Radxa's u-boot SPI image?
Ambian's u-boot configuration is incompatible with Radxa's SPI image
Why Armbian is using u-boot that is incompatible with Radxa's?
It uses mainline u-boot with Open Source TPL/SPL/proper and BL31 from Rockchip packaged into u-boot and we may switch to using open source ATF instead of the BL31 in the future.
Can I boot Radxa's images with Armbian's u-boot written to SPI?

Question
piter75
With Armbian v20.11 one can write mainline u-boot image to board's SPI and enjoy booting nvme drives without any mmc devices.
Prerequisities: ROCK Pi 4(A/B/C) v1.4 or 1.3 with SPI soldered in (v1.3 comes without SPI flash from the factory).
echo spi1.0 > /sys/bus/spi/drivers/spi-nor/bind
ls /dev/mtdblock0
Why bother with mainline u-boot?
It is known to boot some NVMe drives that legacy u-boot from Radxa has issues with, eg. SAMSUNG 970 EVO Plus and SAMSUNG PM981.
This does not mean that all NVMe drives are supported, YMMV.
Which NVMe drives are known to be working?
Corsair MP510 240GB/480GB/960GB

Yes. Armbian's SPI u-boot is compatible with Radxa's images available here: https://github.com/radxa/rock-pi-images-released/releases
It may not be compatible with some older images (released before July 2020) because of the device tree filename change.
