With [1] removing MPCore SMP support, this makes the OX820 barely usable,

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!
Patch 2 obviously depends on [1].

Thanks a lot for going through this and preparing the patches!
I've discussed this with Daniel Golle on the OpenWRT channel as well,
and he indicated that the timing is probably fine here, as there are
already close to zero downloads for oxnas builds, and the 6.1 kernel
will only be part of a release in 2024.
For the dependency on my other patch, I'd suggest you instead
remove the SMP files here as well, which means we can merge either
part independently based on just 6.3-rc. I can do that change
myself by picking up patches 1-4 of your RFC series, or maybe you
can send resend them after rebase to 6.3-rc1.
For the driver removals, I think we can merge those at the same
time as the platform removal since there are no shared header files
that would cause build time regressions and there are no runtime
regressions other than breaking the platform itself. Maybe
just send the driver removal separately to the subsystem
maintainers with my

Sounds reasonable, so also

(but I am a bit sad about it anyway. without SMP it doesn't make sense
to keep ox820 though)
Same !
I would have loved to see the full support mainline, but the platform is
old and apart you nobody were interested in working on this.
Thanks a lot for you work keeping Oxnas support alive!
