busybear: allow testbench to ignore lack of MMU for now
...
I'd really like to go over this with someone else, not sure if this is
a good thing to be doing
If it is, we're at 1M instructions!

busybear: more updates
...
now gets to instruction 839037 before failing
also updates to match new gdb output format
umm there seems to be something wrong with the SSTATUS CSR. Just leaving
it out for now, will come back and check it later

Busybear: next week of updates
...
- move parsed instructions out of git, to /courses/e190ax/busybear_boot
- parsed first 1M instructions, and now parse from split GDB runs
- now at about 230k instructions, can't progress further for now since atomic instructions
aren't implemented yet

Now actually keeping perfectly in line with OVP for the first 100k instrs. Yay.

Busybear: start checking CSRs
...
scounteren and mcounteren are currenly manually deleted from the CSRs list
(see slack channl #linux-bringup)
and 3 of the CSRs referenced are skipped because of weird locations for them
oh and this doesn't check their initial state, just their changing. This could be a problem
