[edk2-devel] [PATCH v3 0/3] ArmPkg, MdeModulePkg: Implement EFI_MP_SERVICES_PROTOCOL for AArch64 and add MpServicesTest application

[Rebecca Cran]

Implement EFI_MP_SERVICES_PROTOCOL based on PSCI calls for AArch64, and
add an MpServicesTest application to exercise it.

Changes from v2:

- Moved definition of MT bit and macro to get affinity bits into
  ArmLib.h.
- Fixed issues noted during review.
- Fixed various issues in non-blocking mode.
- Fixed bugs when a timeout occurs.

Tested on NVIDIA Jetson AGX Orin Developer Kit,
Arm Juno r2.
The RDN2 (Neoverse N2) FVP has problems with caches, but I believe this
is a bug in the model, not the MP Services code.
