I agree. I started with separating common things into new common space and create one for risc-v. However, I dropped that approach for two reasons. 1) The commit "b2bbe3df5470 DynamicTablesPkg: Remove PPTT ID structure from ACPI 6.4 generator" when removed one of the enums from ArmObjectID, didn't change the other values for other enums but reserved the removed one. So, I thought there may be some assumptions which will break if the enum value changes. 2) DynamicPlatformRepositoryInfo structure has ArmCmObjList and ArmCmObjArray. With separate spaces for Arm, RiscV and Common, list management needs some redesign and I was not sure it is worth it. Hence, I thought a single list of all possible Obj Ids for all architectures and common things would be a good trade off. But I can go back to that approach in v2 if above issues are fine. Thanks!
