      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.

      Ensure the flow through switch statements is clear · a08a2014
      Daniel Boulby authored
      
      
      Ensure case clauses:
      *   Terminate with an unconditional break, return or goto statement.
      *   Use conditional break, return or goto statements as long as the end
          of the case clause is unreachable; such case clauses must terminate
          with assert(0) /* Unreachable */ or an unconditional  __dead2 function
          call
      *   Only fallthough when doing otherwise would result in less
          readable/maintainable code; such case clauses must terminate with a
          /* Fallthrough */ comment to make it clear this is the case and
          indicate that a fallthrough is intended.
      
      This reduces the chance of bugs appearing due to unintended flow through a
      switch statement

      qemu: Fix interrupt type check · 53a98be3
      Santeri Salko authored
      
      
      Function plat_ic_get_pending_interrupt_type() should return interrupt
      type, not id. The function is used in aarch64 exception handling and
      currently the irq/fiq forwarding fails if a secure interrupt happens while
      running normal world.
      
      The qemu-specific gic file does not contain any extra functionality so it
      can be removed and common file can be used instead.

      GIC: Introduce API to get interrupt ID · 4ee8d0be
      Jeenu Viswambharan authored
      
      
      Acknowledging interrupt shall return a raw value from the interrupt
      controller in which the actual interrupt ID may be encoded. Add a
      platform API to extract the actual interrupt ID from the raw value
      obtained from interrupt controller.
      
      Document the new function. Also clarify the semantics of interrupt
      acknowledge.

      Prepare platforms to use refactored ARM GIC drivers · f14d1886
      Soby Mathew authored
      This patch adds platform helpers for the new GICv2 and GICv3 drivers in
      plat_gicv2.c and plat_gicv3.c. The platforms can include the appropriate
      file in their build according to the GIC driver to be used. The existing
      plat_gic.c is only meant for the legacy GIC driver.
      
      In the case of ARM platforms, the major changes are as follows:
      
      1. The crash reporting helper macro `arm_print_gic_regs` that prints the GIC CPU
         interface register values has been modified to detect the type of CPU
         interface being used (System register or memory mappped interface) before
         using the right interface to print the registers.
      
      2. The power management helper function that is called after a core is powered
         up has been further refactored. This is to highlight that the per-cpu
         distributor interface should be initialised only when the core was originally
         powered down using the CPU_OFF PSCI API and not when the CPU_SUSPEND PSCI API
         was used.
      
      3. In the case of CSS platforms, the system power domain restore helper
         `arm_system_pwr_domain_resume()` is now only invoked in the `suspend_finish`
         handler as the system power domain is always expected to be initialized when
         the `on_finish` handler is invoked.
