      GICv3: GIC-600: Detect GIC-600 at runtime · b4ad365a
      Andre Przywara authored
      
      
      The only difference between GIC-500 and GIC-600 relevant to TF-A is the
      differing power management sequence.
      A certain GIC implementation is detectable at runtime, for instance by
      checking the IIDR register. Let's add that test before initiating the
      GIC-600 specific sequence, so the code can be used on both GIC-600 and
      GIC-500 chips alike, without deciding on a GIC chip at compile time.
      
      This means that the GIC-500 "driver" is now redundant. To allow minimal
      platform support, add a switch to disable GIC-600 support.

      FVP: Fix BL31 load address and image size for RESET_TO_BL31=1 · 6227cca9
      Alexei Fedorov authored
      
      
      When TF-A is built with RESET_TO_BL31=1 option, BL31 is the
      first image to be run and should have all the memory allocated
      to it except for the memory reserved for Shared RAM at the start
      of Trusted SRAM.
      This patch fixes FVP BL31 load address and its image size for
      RESET_TO_BL31=1 option. BL31 startup address should be set to
      0x400_1000 and its maximum image size to the size of Trusted SRAM
      minus the first 4KB of shared memory.
      Loading BL31 at 0x0402_0000 as it is currently stated in
      '\docs\plat\arm\fvp\index.rst' causes EL3 exception when the
      image size gets increased (i.e. building with LOG_LEVEL=50)
      but doesn't exceed 0x3B000 not causing build error.

      doc: Split the User Guide into multiple files · 43f35ef5
      Paul Beesley authored
      
      
      The User Guide document has grown organically over time and
      now covers a wide range of topics, making it difficult to
      skim read and extract information from. Currently, it covers
      these topics and maybe a couple more:
      
      - Requirements (hardware, tools, libs)
      - Checking out the repo
      - Basic build instructions
      - A comprehensive list of build flags
      - FIP packaging
      - Building specifically for Juno
      - Firmware update images
      - EL3 payloads
      - Preloaded BL33 boot flow
      - Running on FVPs
      - Running on Juno
      
      I have separated these out into a few groups that become new
      documents. Broadly speaking, build instructions for the tools,
      for TF-A generally, and for specific scenarios are separated.
      Content relating to specific platforms (Juno and the FVPs are
      Arm-specific platforms, essentially) has been moved into the
      documentation that is specific to those platforms, under
      docs/plat/arm.
