In addition, the OX810 hasn't been booted for years and isn't even present in an ARM config file. For the OX820, lack of USB and SATA support makes the platform not usable in the current Linux support and relies on off-tree drivers hacked from the vendor (defunct for years) sources. The last users are in the OpenWRT distribution, and today's removal means support will still be in stable 6.1 LTS kernel until end of 2026. If someone wants to take over the development even with lack of SMP, I'll be happy to hand off maintainance. The plan is to apply the first 4 patches first, then the drivers followed by bindings. Finally the MAINTAINANCE entry can be removed. I'm not sure about the process of bindings removal, but perhaps the bindings should be marked as deprecated first then removed later on ? It has been a fun time adding support for this architecture, but it's time to get over!
