2023-09-08MdePkg/Rng: Add GetRngGuid() to RngLibPierre Gondois2-0/+32
The EFI_RNG_PROTOCOL can use the RngLib. The RngLib has multiple implementations, some of them are unsafe (e.g. BaseRngLibTimerLib). To allow the RngDxe to detect when such implementation is used, add a GetRngGuid() function to the RngLib.

2023-09-08SecurityPkg/SecurityPkg.dec: Move PcdCpuRngSupportedAlgorithm to MdePkgPierre Gondois1-1/+1
In order to use PcdCpuRngSupportedAlgorithm in the MdePkg in a following patch and to avoid making the MdePkg dependent on another package, move PcdCpuRngSupportedAlgorithm to the MdePkg. As the Pcd is only used for AARCH64, place it in an AARCH64 specific sections.

2023-09-08MdeModulePkg: Duplicate BaseRngLibTimerLib to MdeModulePkgPierre Gondois3-0/+243
BZ: https://bugzilla.tianocore.org/show_bug.cgi?id=4504 The BaseRngLibTimerLib allows to generate number based on a timer. This mechanism allows to have a basic non-secure implementation for non-production platforms. To bind and identify Random Number Generators implementations with a GUID, an unsafe GUID should be added. This GUID cannot be added to the MdePkg unless it is also added to a specification. To keep the MdePkg self-contained, copy the BaseRngLibTimerLib to the MdeModulePkg. This will allow to define an unsafe Rng GUID in a later patch in the MdeModulePkg. The MdePkg implementation will be removed later. This allows to give some time to platform owners to switch to the MdeModulePkg implementation.
