      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.

      plat/arm/sgi: introduce number of chips macro · 4d37aa76
      Vijayenthiran Subramaniam authored
      
      
      Introduce macro 'CSS_SGI_CHIP_COUNT' to allow Arm CSS platforms with
      multi-chip support to define number of chiplets on the platform. By
      default, this flag is set to 1 and does not affect the existing single
      chip platforms.
      
      For multi-chip platforms, override the default value of
      CSS_SGI_CHIP_COUNT with the number of chiplets supported on the
      platform. As an example, the command below sets the number of chiplets
      to two on the RD-N1-Edge multi-chip platform:
      
      export CROSS_COMPILE=<path-to-cross-compiler>
      make PLAT=rdn1edge CSS_SGI_CHIP_COUNT=2 ARCH=aarch64 all

      Adds option to read ROTPK from registers for FVP · a6ffddec
      Max Shvetsov authored
      
      
      Enables usage of ARM_ROTPK_LOCATION=regs for FVP board.
      Removes hard-coded developer keys. Instead, setting
      ARM_ROTPK_LOCATION=devel_* takes keys from default directory.
      In case of ROT_KEY specified - generates a new hash and replaces the
      original.
      
      Note: Juno board was tested by original feature author and was not tested
      for this patch since we don't have access to the private key. Juno
      implementation was moved to board-specific file without changing
      functionality. It is not known whether byte-swapping is still needed
      for this platform.

      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.
