10.1 EDK, mch_opb_ddr_v1_00_c - MCH_OPB_DDR controller does unnecessary precharge when accessing the same row address

Description

When using mch_opb_ddr_v1_00_c EDK DDR controller, additional precharges are performed that are not necessary due to the use of open row management. How do I resolve this issue?

Solution

This issue might reduce performance but should not cause data errors. This issue is not planned to be fixed since this core is no longer being actively developed.
