Rockchip SoCs are shipped with a unique CPU ID in their internal OTP memory, and Rockchip bootloaders use it to give boards which have no dedicated storage for a MAC address a stable one anyway: they hash the CPU ID and patch the resulting addresses into the device tree they hand over. Kernels started without that fixup, e.g. straight from the SPL in Falcon mode or by any other loader which does not implement Rockchip's derivation, fall back to random MAC addresses which change on every boot.

Applied, thanks!
