for the whole pi0-pi4 family, an armstub from here is dropped at the arm reset vector
its responsible for doing things like initial register setup, parking the secondary cores, and dropping down to EL1 before running your kernel
I do believe RPi kernel starts in EL2, otherwise KVM would not be able to work properly
