Make tests safe to run in parallel
...
For example using pytest-parallel you can greatly reduce time it takes
to run all tests.
```
$ pytest --workers auto test

frontend/AXI: Add optional Read-Modify-Write mode for cases where w.strb is not available on the DRAM side (ex when ECC is enabled).
...
When enabled, partial writes are automatically detected and a Read-Modify-Write access is
done. Before doing a RMW access, pending accesses are terminated and incoming accesses are
stalled until RMW access is done.
Enable with_read_modify_write in test_axi.

phy/lpddr4: fix edge case error with CommandsPipeline ignoring a command
...
Command was being ignored when it occurred on the last phase and
the next command would invalidate the first phase. Now it is fixed
and a regression test is included. A fix in ConstBitSlip has been added
due to wrong Verilog being generated with cycles=1, register=False.
