Anton Blanchard fe1bb083ef litedram_gen: Fix error with --sim option 
It looks like commit 317072a198 ("litedram_gen: Add initial SDRAM
support (with ULX3S example)") broke building with the --sim option.

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.

Jędrzej Boczar baf9c07858 phy/utils: improve ConstBitSlip: 
* optional register=False to decrease latency by 1 cycle

  still can be used)
* add unit tests

Florent Kermarrec d16aaa7456 frontend/ecc: Add optional Write errors detection (checking granularity). 
Write granularity has been recently reduced from DRAM's full burst data-width to DRAM's data-width.
This can avoid read-modify-write pattern from User logic, but we also need to be sure
the User logic will not generate partial access or adjust the granularity correctly.

The new with_we_error_detection paramter can be set to True to enable Write granularity errors
and can ease debug.
