c796547156 greatly improved PLIC register interface 2021-04-22 11:22:01 -04:00

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

5902637632 buildroot: sim is now running! 
yes it only gets through 5 instructions right now. Yes that's my fault.

541fb22dc9 start to add buildroot testbench
