      Enable MTE support in both secure and non-secure worlds · 9dd94382
      Justin Chadwell authored
      
      
      This patch adds support for the new Memory Tagging Extension arriving in
      ARMv8.5. MTE support is now enabled by default on systems that support
      at EL0. To enable it at ELx for both the non-secure and the secure
      world, the compiler flag CTX_INCLUDE_MTE_REGS includes register saving
      and restoring when necessary in order to prevent register leakage
      between the worlds.

      AArch64: Disable Secure Cycle Counter · e290a8fc
      Alexei Fedorov authored
      
      
      This patch fixes an issue when secure world timing information
      can be leaked because Secure Cycle Counter is not disabled.
      For ARMv8.5 the counter gets disabled by setting MDCR_El3.SCCD
      bit on CPU cold/warm boot.
      For the earlier architectures PMCR_EL0 register is saved/restored
      on secure world entry/exit from/to Non-secure state, and cycle
      counting gets disabled by setting PMCR_EL0.DP bit.
      'include\aarch64\arch.h' header file was tided up and new
      ARMv8.5-PMU related definitions were added.
