Hi,
thanks for all the efforts in getting those SoC peripherals supported!

So because of this, the Allwinner R528 and T113 SoCs would share almost
everything in this file. Would it be useful to already split this DT up?
To have a base .dtsi, basically this file without /cpus and /soc/plic,
then have a RISC-V specific file with just those, including the base?
There is precedence for this across-arch(-directories) sharing with the
Raspberry Pi and Allwinner H3/H5 SoCs.
Or do you plan to leave that for when support for the ARM core versions is
actually submitted? But I don't think we need any extra *code* for that,
it's just the DT?
Cheers,
Andre.
