With the previous code lines included python variable names instead of integers, e.g.
("ZQ Calibration start", MPC.ZQC_START, SpecialCmd.MPC, dfii_command_we|dfii_command_cs, 200)
which failed as these names were not being imported.

This is needed because newer DRAMs like LPDDR4 or DDR5 have
separate commands for per-bank refresh and all banks refresh.
Other DRAM types ignore address for REF commands.
