a861a37b72 Why was the linter messed up? 
There are a number of combo loops which need fixing outside the icache.  They may be fixed in main.
We get to instruction address 50 now!

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

yes it only gets through 5 instructions right now. Yes that's my fault.

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'
