* for now, /rel is the original and /dev has updates:
* compiles with verilator, iverilog, yosys
* runs simple version of kernel/bios/random test with cocotb (A2L2 interface partially implemented in Python) and Verilog core wrapper (A2L2<->mem interface)
* runs simple version of kernel/bios/random test with cocotb (A2L2 interface partially implemented in Python) and Verilog core wrappers (A2L2<->mem/wb interfaces)
* wrapper converts A2L2 interface to mem and Wishbone interfaces
