Some observations of what is not in this patchset:

* There is neither /memreserve/ nor /reserved-memory here. What about
Boot ROM, TEE and RPC?
* The reset controllers for the UARTs are missing. Can we take the same
shortcut as in my RTD1395 patch to add them now, i.e. are they
compatible with RTD1295?
* Is the watchdog incompatible, or is it just not enabled by the
bootloader and depends on future, e.g., clk patches?
* Is the RTC not enabled on boot, similar to the other SoCs?

Regards,
Andreas
