That's a good idea. But I think that one should also already take the work by brainslayer into
account which adds a lot to the initial SoC configuration:
https://github.com/BrainSlayer/pie/tree/pie-5.10-rtl9313/target/linux/realtek/files-5.10/arch/mips/rtl838x
What we put in now should already anticipate the use of SMP (from 839x onwards), and for the 931x the GIC as the new
Interrupt controller, large memory support and the GIC timer.
