      doc: Use proper note and warning annotations · e1c5026a
      Paul Beesley authored
      The documentation contains plenty of notes and warnings. Enable
      special rendering of these blocks by converting the note prefix
      into a .. note:: annotation.

      doc: Set correct syntax highlighting style · 29c02529
      Paul Beesley authored
      Several code blocks do not specify a language for syntax
      highlighting. This results in Sphinx using a default highlighter
      which is Python.
      
      This patch adds the correct language to each code block that doesn't
      already specify it.

      doc: Remove per-page contents lists · 57354abb
      Paul Beesley authored
      These are no longer needed as there will always be a table of contents
      rendered to the left of every page.
      
      Some of these lists can be quite long and, when opening a page, the
      reader sees nothing but a huge list of contents! After this patch,
      the document contents are front-and-centre and the contents are
      nicely rendered in the sidebar without duplication.

      doc: Reformat platform port documents · 24dba2b3
      Paul Beesley authored
      The platform port documents are not very standardised right now and
      they don't integrate properly into the document tree so:
      
      1) Make sure each port has a proper name and title (incl. owner)
      2) Correct use of headings, subheadings, etc in each port
      3) Resolve any naming conflicts between documents

      doc: Move documents into subdirectories · 40d553cf
      Paul Beesley authored
      This change creates the following directories under docs/
      in order to provide a grouping for the content:
      
      - components
      - design
      - getting_started
      - perf
      - process
      
      In each of these directories an index.rst file is created
      and this serves as an index / landing page for each of the
      groups when the pages are compiled. Proper layout of the
      top-level table of contents relies on this directory/index
      structure.
      
      Without this patch it is possible to build the documents
      correctly with Sphinx but the output looks messy because
      there is no overall hierarchy.

      Support booting OP-TEE as BL32 boot stage and secure runtime
      service.
      
      OP-TEE executes in internal RAM and uses a secure DDR area to store
      the pager pagestore. Memory mapping and TZC are configured accordingly
      prior OP-TEE boot. OP-TEE image is expected in OP-TEE v2 format where
      a header file describes the effective boot images. This change
      post processes header file content to get OP-TEE load addresses
      and set OP-TEE boot arguments.

      Tegra: Support for scatterfile for the BL31 image · c2ad38ce
      Varun Wadekar authored
      This patch provides support for using the scatterfile format as
      the linker script with the 'armlink' linker for Tegra platforms.
      
      In order to enable the scatterfile usage the following changes
      have been made:
      
      * provide mapping for ld.S symbols in bl_common.h
      * include bl_common.h from all the affected files
      * update the makefile rules to use the scatterfile and armlink
        to compile BL31
      * update pubsub.h to add sections to the scatterfile
      
      NOTE: THIS CHANGE HAS BEEN VERIFIED WITH TEGRA PLATFORMS ONLY.

      Tegra: lib: library for profiling the cold boot path · 087cf68a
      Varun Wadekar authored
      The non secure world would like to profile the boot path for
      the EL3 and S-EL1 firmwares. To allow it to do that, a non-secure
      DRAM region (4K) is allocated and the base address is passed to
      the EL3 firmware.
      
      This patch adds a library to allow the platform code to store the
      tag:timestamp pair to the shared memory. The tegra platform code
      then uses the `record` method to add timestamps.

      rpi3: add RPI3_USE_UEFI_MAP build option · 4dcf1fad
      Pete Batard authored
      The default Raspberry Pi 3 memory mapping for ATF is geared towards
      the use of uboot + Linux. This creates issues when trying to use
      ATF with an UEFI payload and Windows on ARM64.
      
      We therefore introduce new build option RPI3_USE_UEFI_MAP, that
      enables the build process to use an alternate memory mapping that
      is compatible with UEFI + Windows (as well as UEFI + Linux).

      rpi3: add RPI3_RUNTIME_UART build option · 6d5c61de
      Pete Batard authored
      Some OSes (e.g. Ubuntu 18.04 LTS on Raspberry Pi 3) may disable the
      runtime UART in a manner that prevents the system from rebooting if
      ATF tries to send runtime messages there.
      
      Also, we don't want the firmware to share the UART with normal
      world, as this can be a DoS attack vector into the secure world.
      
      This patch fixes these 2 issues by introducing new build option
      RPI3_RUNTIME_UART, that disables the runtime UART by default.

      rpi3: Add mem reserve region to DTB if present · 5341b42e
      Antonio Nino Diaz authored
      When a device tree blob is present at a known address, instead of, for
      example, relying on the user modifying the Linux command line to warn
      about the memory reserved for the Trusted Firmware, pass it on the DTB.
      
      The current code deletes the memory reserved for the default bootstrap
      of the Raspberry Pi and adds the region used by the Trusted Firmware.
      
      This system replaces the previous one consisting on adding
      ``memmap=16M$256M`` to the Linux command line. It's also meant to be
      used by U-Boot and any other bootloader that understands DTB files.

      Overview
      ---------
      
      BOOTROM starts the cpu at EL3; In this port BL2 will therefore be entered
      at this exception level (the Renesas' ATF reference tree [1] resets into
      EL1 before entering BL2 - see its bl2.ld.S)
      
      BL2 initializes DDR (and i2c to talk to the PMIC on some platforms)
      before determining the boot reason (cold or warm).
      
      During suspend all CPUs are switched off and the DDR is put in
      backup mode (some kind of self-refresh mode). This means that BL2 is
      always entered in a cold boot scenario.
      
      Once BL2 boots, it determines the boot reason, writes it to shared
      memory (BOOT_KIND_BASE) together with the BL31 parameters
      (PARAMS_BASE) and jumps to BL31.
      
      To all effects, BL31 is as if it is being entered in reset mode since
      it still needs to initialize the rest of the cores; this is the reason
      behind using direct shared memory access to  BOOT_KIND_BASE and
      PARAMS_BASE instead of using registers to get to those locations (see
      el3_common_macros.S and bl31_entrypoint.S for the RESET_TO_BL31 use
      case).
      
      Depending on the boot reason BL31 initializes the rest of the cores:
      in case of suspend, it uses a MBOX memory region to recover the
      program counters.
