      Sanitise includes across codebase · 09d40e0e
      Antonio Nino Diaz authored
      Enforce full include path for includes. Deprecate old paths.
      
      The following folders inside include/lib have been left unchanged:
      
      - include/lib/cpus/${ARCH}
      - include/lib/el3_runtime/${ARCH}
      
      The reason for this change is that having a global namespace for
      includes isn't a good idea. It defeats one of the advantages of having
      folders and it introduces problems that are sometimes subtle (because
      you may not know the header you are actually including if there are two
      of them).
      
      For example, this patch had to be created because two headers were
      called the same way: e0ea0928 ("Fix gpio includes of mt8173 platform
      to avoid collision."). More recently, this patch has had similar
      problems: 46f9b2c3 ("drivers: add tzc380 support").
      
      This problem was introduced in commit 4ecca339
      
       ("Move include and
      source files to logical locations"). At that time, there weren't too
      many headers so it wasn't a real issue. However, time has shown that
      this creates problems.
      
      Platforms that want to preserve the way they include headers may add the
      removed paths to PLAT_INCLUDES, but this is discouraged.

      CSS:Fix scpi "get_power_state" when ARM_PLAT_MT is set · 878a8bdf
      jagadeesh ujja authored
      
      
      The ARM_PLAT_MT bit enables the support for MT bit in
      MPIDR format. This means that the level 0 affinity
      represents the thread and CPU / Cluster levels are
      at affinity level 1 and 2 respectively.
      This was not catered for in the scpi 'css_scp_get_power_state, API.
      Since the SCPI driver can only cater for single threaded CPUs,
      this patch fixes the problem by catering for this shift by
      effectively ignoring the Thread (level 0) affinity level.

      css: Ensure PSCI system off/reset is not interrupted · 0498343a
      dp-arm authored
      
      
      If there is a pending interrupt, it is possible for the AP to come out
      of the final WFI before SCP has a chance to act on it.  Prevent this
      by disabling the GIC CPU interface before issuing a WFI.
      
      Previously, SCP would not wait on WFI before taking an action but
      would shut down the core or system regardless.

      Introduce SCP power management abstraction · b12a2b49
      Soby Mathew authored
      
      
      This patch introduces an additional layer of abstraction between
      CSS power management hooks and the SCPI driver. A new set of APIs
      are introduced in order to abstract out power management operations
      from underlying communication mechanism with the SCP.
      
      The SCPI and the associated MHU drivers are moved into a `drivers`
      folder in CSS. The new SCP communication abstraction layer is added
      in the `drivers/scp` folder. The existing CSS power management
      uses the new APIs to reflect this abstraction.
