Florent Kermarrec 62845f1ec9 phy/usddrphy: update header with 1333, 1866 MT/s. 2020-12-10 08:44:05 +01:00
Florent Kermarrec 496cd27a3d phy/s7/usddrphy: set default cmd_latency to 0.
Now that we are restricting cmd/clk scan in liblitedram, cmd_latency=0 seems
to be workin for all configurations.

Florent Kermarrec 68cd462bd4 ci: migrate from Travis CI to Github Actions.
Only covers unit-tests for now, Verilator simulation and benchmarks still need to be adapted.

Greg Davill 0c8c707f24 ecp5ddrphy: Fix DELAYF initial value
I've seen intermittent failures with recent builds. I suspect it is
related to the DELAYF primitive not being correctly loaded with an
initial value. Holding LOADN LOW ensures a value is correctly
loaded.
