      Switch AARCH32/AARCH64 to __aarch64__ · 402b3cf8
      Julius Werner authored
      
      
      NOTE: AARCH32/AARCH64 macros are now deprecated in favor of __aarch64__.
      
      All common C compilers pre-define the same macros to signal which
      architecture the code is being compiled for: __arm__ for AArch32 (or
      earlier versions) and __aarch64__ for AArch64. There's no need for TF-A
      to define its own custom macros for this. In order to unify code with
      the export headers (which use __aarch64__ to avoid another dependency),
      let's deprecate the AARCH32 and AARCH64 macros and switch the code base
      over to the pre-defined standard macro. (Since it is somewhat
      unintuitive that __arm__ only means AArch32, let's standardize on only
      using __aarch64__.)

      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.

      qemu: support ARMv7/Cortex-A15 · 765ed9fc
      Etienne Carriere authored
      
      
      Define Qemu AArch32 implementation for some platform functions
      (core position, secondary boot cores, crash console). These are
      derived from the AArch64 implementation.
      
      BL31 on Qemu is needed only for ARMv8 and later. On ARMv7, BL32 is
      the first executable image after BL2.
      
      Support SP_MIN and OP-TEE as BL32: create a sp_min make script target
      in Qemu, define mapping for IMAGE_BL32
      
      Minor fix Qemu return value type for plat_get_ns_image_entrypoint().
      
      Qemu model for the Cortex-A15 does not support the virtualization
      extension although the core expects it. To overcome the issue, Qemu
      ARMv7 configuration set ARCH_SUPPORTS_VIRTUALIZATION to 0.
      
      Add missing AArch32 assembly macro arm_print_gic_regs from ARM platform
      used by the Qemu platform.
      
      Qemu Cortex-A15 model integrates a single cluster with up to 4 cores.

      qemu: Add OP-TEE extra image parsing support · e2af1cad
      Jens Wiklander authored
      
      
      OP-TEE may have extra images to be loaded. Load them one by one and do
      the parsing. In this patch, ARM TF need to load up to 3 images for
      OP-TEE: header, pager and pages images. Header image is the info about
      optee os and images. Pager image include pager code and data.  Paged
      image include the paging parts using virtual memory.

      qemu: Add LOAD_IMAGE_V2 support · 64b31125
      Fu Wei authored
      
      
      The generic LOAD_IMAGE_V2 framework has been merged and enable for almost
      all the arm platform. Because qemu platform doesn't share those common
      files with arm, QEMU haven't got this support yet.
      
      This patch add all the necessary code the files for adding LOAD_IMAGE_V2
      support on QEMU and enable it as default.
      
      Fixes ARM-software/tf-issues#507
