395 Incorrect Data Masking in Ganged DRAM Mode
Description
The DRAM controller may apply incorrect DRAM data masks when operating in ganged mode
(DRAM Controller Select Low Register[DctGangEn] (F2x110[4]) is set to 1b).
Potential Effect on System
Unpredictable system behavior.
Suggested Workaround
The DRAM controllers should only be configured in the unganged mode. BIOS should not set
DRAM Controller Select Low Register[DctGangEn] (F2x110[4]). When only a single DCT is in use,
DctGangEn is always zero.
Fix Planned
Yes
