* for now, /rel is the original and /dev has updates:
* compiles with verilator, iverilog, yosys
* runs original simple boot code up to test invocation with cocotb (A2L2 interface partially implemented in Python)
* runs simple version of kernel/bios/random test with cocotb (A2L2 interface partially implemented in Python) and Verilog core wrapper (A2L2<->mem interface)
* verilator builds, but does not simulate correctly
