4f97e9e761 start to add buildroot testbench 
This still uses testbench-busybear.sv
I think it might be time to finally rename nearly 'busybear' thing to 'linux'

d66fcbc4ab busybear: use (slightly) less terrible verilog 2021-04-14 00:18:44 -04:00
Noah Boorstin
c75455cc41 busybear testbench updates 
start speculative checking on CSR* satp, *
add some slight delays in some CSR checkings to make them deterministic

I realize this verilog is incredibly un-idiomatic. But I still don't
know of anything better. If you figure it out, please let me know
