Hacked the sram memory models to reset their internal registers. This allows the simulation to run but is only temporary.

About 149307ns of simulation run.

Wrote a bash script to generate custom modelsim radix which maps instruction addresses into human readable lables.
...
Once combined with some simulation verilog this will display the current function in modelsim.

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: 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
