Michal Sieron a912a88081 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
```

Florent Kermarrec 095180be6a 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.

Jędrzej Boczar 8c10f1405b phy/lpddr5: delay WCK sync FSM transition by 1 cycle 
With fixed serialization logic WCK sync can be now started later
which avoids the need for special logic when tWCKENL=0.

Jędrzej Boczar da769094fd 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.
 2021-06-22 11:40:51 +02:00
Jędrzej Boczar baf9c07858 phy/utils: improve ConstBitSlip: 
* optional register=False to decrease latency by 1 cycle
* require explicit `cycles` as it influences latency (min_cycles
  still can be used)
* add unit tests
