PlatGen errors with mch_opb_emc_v1_01_a core result from the following incorrect Range setting in the MPD per the new enhancements.
1. The PARAMETER C_NUM_BANKS_MEM = 1, DT = INTEGER, RANGE = (1) is incorrectly defined in mch_opb_emc_v1_01_a .
The range should be set from 1-4 in MPD, (RANGE = (1:4)).
2. The PARAMETER C_NUM_CHANNELS = 2, DT = INTEGER, RANGE = (1:4) is incorrectly defined.
The range should be from 0:4 in the MPD (RANGE = (0:4)).
The MPD will be fixed for mch_opb_emc_v1_01_a in the next release of EDK 9.1i SP1.
Meanwhile, to prevent the PlatGen errors, edit the MPD file for the mch_opb_emc_v1_01_a to the correct Range setting as described above. The correct Range is documented in the mch_opb_emc_v1_01_a Data sheet.
