      feat(plat/sgi): introduce platform variant build option · cfe1506e
      Aditya Angadi authored
      
      
      A Neoverse reference design platform can have two or more variants that
      differ in core count, cluster count or other peripherals. To allow reuse
      of platform code across all the variants of a platform, introduce build
      option CSS_SGI_PLATFORM_VARIANT for Arm Neoverse reference design
      platforms. The range of allowed values for the build option is platform
      specific. The recommended range is an interval of non negative integers.
      
      An example usage of the build option is
      make PLAT=rdn2 CSS_SGI_PLATFORM_VARIANT=1

      Add SiP service to configure Arm Ethos-N NPU · 76a21174
      Mikael Olsson authored
      
      
      By default the Arm Ethos-N NPU will boot up in secure mode. In this mode
      the non-secure world cannot access the registers needed to use the NPU.
      To still allow the non-secure world to use the NPU, a SiP service has
      been added that can delegate non-secure access to the registers needed
      to use it.
      
      Only the HW_CONFIG for the Arm Juno platform has been updated to include
      the device tree for the NPU and the platform currently only loads the
      HW_CONFIG in AArch64 builds.

      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.
