I have RPi2 and it has Cortex A7 AFAIK.

I was able to boot to uefi shell. What can I do further? What is my
overall goal? To build and run several instances of Linux? Make a
patch?

I have also proposed to make a port of xen for qemu-system-riscv (it
should be ready in Q2.2018) to people from riscv but I haven't
received any answer.Anyway, I would like to work with xen on embedded
platforms.
