      AArch64: Enable MPAM for lower ELs · 5f835918

      Memory Partitioning And Monitoring is an Armv8.4 feature that enables
      various memory system components and resources to define partitions.
      Software running at various ELs can then assign themselves to the
      desired partition to control their performance aspects.
      
      With this patch, when ENABLE_MPAM_FOR_LOWER_ELS is set to 1, EL3 allows
      lower ELs to access their own MPAM registers without trapping to EL3.
      This patch however doesn't make use of partitioning in EL3; platform
      initialisation code should configure and use partitions in EL3 if
      required.
