c7a09d2359 yay buildroot passes a decent amount of tests now
gets through the first 15k instructions, that's good enough for now
also slight change to string parsing in busybear testbench

541fb22dc9 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'

3e0ed5a2b1 busybear: use (slightly) less terrible verilog 2021-04-14 00:18:44 -04:00
Noah Boorstin
18a4d5fc8d 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
