In addition to RPi hardware, it would be helpful to support Rockchip RK3399 and RK3588 SoCs that have minimal binary blobs, since these can used with open-source Arm Trusted Firmware (TF-A) for secure boot, to ensure that only owner-authorized OS and firmware are running on the device.

Do these M.2 WiFi cards support AP/VLAN and BSSID updates?
Just so people don't get confused, there is a huge world of difference between these two chips. They are not in the same category.
Rockchip RK3399 is 100% blobless. You even control the EL3 Trustzone Secure World! This is True Root.
Rockchip RK3588 still needs blobs in EL3, the highest privilege level. We've been hearing rumors for years now about "oh they'll open source it next month for sure" and it.... just. never. happens. Please stop spreading this rumor. Source or GTFO, Rockchip.
> Rockchip have sent a few patches to the TF-A project here to support [RK3588].. From TF-A we can now build a complete working BL31 and replace the closed binary blob with an open-source binary that we can compile ourselves.. There are still some missing parts and the most important that is remaining right now is the DDR training blob, which is still closed source.
Cleanroom reverse engineering for the purpose of publishing new driver code, to avoid legal/IP minefields, is super-expensive. It should be a much narrower scope to determine whether a binary blob's actions are limited to memory training, since there is no requirement to publish reusable source code.
Looks like Collabora is already monitoring the blob, so it's not entirely a mystery:
At the moment of writing this article, we have identified a few differences from the binary blob previously used, which we can highlight as following:
Binary BL31 contains some unknown code to get HDMI-RX PHY access working.
The cpufreq support in binary BL31 is different from TF-A.
There could be more issues that are unknown at the moment and users should be aware of it.
> That doesn't sound like DDR training to me. Maybe now you see the problem?
It is absolutely a problem, but it's bounded by the ability to inspect and question code/behavior outside the officially claimed rationale. We can prefer open systems and also shine a bright light on the behavior of closed systems.
SPR can run about anywhere docker can run. So if you have a linux system running docker with these, you should be good to go. We provide the OS images as one path to running SPR.
We are currently looking at banana pi over rockchip but we are very happy to assist if someone has this gear.
I don't have access to Qualcomm information but if you have those chips it will be under the output of 'iw dev'.
