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

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
