Why not protonic-rk35xx or something even more generic? protonic-prtpuk is
already mainlined and the code is very similar to this branch. IMHO it should
also be merged. Q4/2026 the RK36xx family is being launched. We don't know yet
whether it will be sufficiently similar/compatible to warrant a hypothetical
protonic board to also be added here?

Best regards,
