I am not sure I understood what you want to move to the ArmPkg.
Nonetheless, doing the following removes the dependency over the ArmPkg
(and it seems to be the normal way way of removing dependencies):
+ TrngLib|MdePkg/Library/BaseTrngLibNull/BaseTrngLibNull.inf
- TrngLib|ArmPkg/Library/ArmFwTrngLib/ArmFwTrngLib.inf
- ArmMonitorLib|ArmPkg/Library/ArmMonitorLib/ArmMonitorLib.inf
- ArmSmcLib|ArmPkg/Library/ArmSmcLib/ArmSmcLib.inf
- ArmHvcLib|ArmPkg/Library/ArmHvcLib/ArmHvcLib.inf
The only other dependecy over the ArmPkg is the ArmHasRngExt() call in
[PATCH v3 20/21] SecurityPkg/RngDxe: Add Arm support of RngDxe
but this can be easily replaced.
Would it be ok ?
Regards,
Pierre
