Merge branch 'bp' into main

Concerns:
1. I don't think the correct data buses are going to the multiplier.
2. I'm not sure the FlushF signal is correct.

Shreya and I found a bug with the exeuction of JAL and JALR instructions. The link was only set in the writeback stage. Once the branch predictor started correctly predicting JAL(R)s the ALU and forwarding logic need to have the PCLinkE at the execution stage in case an instruction in the next two clocks need the data.

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
