[StevenHuang0117]

We have one system has 1476 nodes of the iort table below: ... IORT node offset:1C2B8, type: 5 IORT node offset:F00, type: 4 IORT node offset:1C2E0, type: 5 IORT node offset:F6C, type: 4 IORT node offset:1C308, type: 5 IORT node offset:F6C, type: 4 IORT node offset:1C330, type: 5 IORT node offset:FD8, type: 4 IORT node offset:1C358, type: 5 IORT node offset:FD8, type: 4 IORT node offset:1C380, type: 5 IORT node offset:1044, type: 4 IORT node offset:1C3A8, type: 5 IORT node offset:1044, type: 4 Number of IOVIRT blocks = 1476 ITS Group Num ITS: 1 ITS ID: 2 ITS Group Num ITS: 1 ITS ID: 3 ITS Group Num ITS: 1 ITS ID: 5 ITS Group Num ITS: 1 ITS ID: 6 ITS Group Num ITS: 1 ...

And Bsa will produce some errors below： ... 228 : Check GIC Maintenance PPI Assignment START

We modify IOVIRT table size to 1M bytes, Bsa run OK. The UEFI Sbsa, Bsa and Sbsa of linux-acs has same problem too.
