But Pomelo is the *board* name, right? Is there some name for the
*cores*? Are those ARM Cortex cores? If yes, use their names (e.g.
"arm,cortex-a72"). Otherwise, use some vendor specific name (Xiaomi,
Mars?). And we don't keep an "arm,armv8" around.

Sorry, I don't think this is correct. First, there need to be two cells
for the reg, as you specify this (rightly so) above.
But more importantly: the "reg" cells need to match the (masked) MPIDR
values of the actual cores (otherwise SMP won't work), and the
"cpu@<xxx>" value has just to follow this. So it should look like:
+ cpu6: cpu at 300 {
+ device_type = "cpu";
+ compatible = "phytium,d2000";
+ reg = <0x0 0x300>;
+ enable-method = "psci";
+ };
So you can keep the numbering for the alias (cpu6:), but copy the "reg"
value into the node name, removing any leading zeros (cpu at 300).

Shouldn't this match the .dts filename used above (phytium,pomelo.dtb)?
Cheers,
