Jędrzej Boczar a4fb1a633a phy/lpddr5: do not use dataclasses for Python 3.6 compatibility 2021-10-26 12:22:30 +02:00
Jędrzej Boczar 9795d6902c phy/lpddr5/sim: partially disable DFITimingsChecker when --disable-delay is on 
With --disable-delay the software won't insert delays in between
commands during memory training which results in DFITimingsChecker
reporting timing violations. With this change we disable
DFITimingsChecker until software completes memory initialization.

Timestamps were completely wrong for WCK as it is disabled
until the first write command and has varying frequency.
Now we use another clock which is always on to calculate time.
