      Mbed TLS: Remove weak heap implementation · 2374ab17
      Ambroise Vincent authored
      
      
      The implementation of the heap function plat_get_mbedtls_heap() becomes
      mandatory for platforms supporting TRUSTED_BOARD_BOOT.
      
      The shared Mbed TLS heap default weak function implementation is
      converted to a helper function get_mbedtls_heap_helper() which can be
      used by the platforms for their own function implementation.

      plat: imx8m: Add the basic support for imx8mm · 179f82a2
      Jacky Bai authored
      
      
      The i.MX8M Mini is new SOC of the i.MX8M family. it is
      focused on delivering the latest and greatest video and
      audio experience combining state-of-the-art media-specific
      features with high-performance processing while optimized
      for lowest power consumption. The i.MX 8M Mini Media Applications
      Processor is  14nm FinFET product of the growing i.MX8M family
      targeting the consumer & industrial market. It is built in 14LPP
      to achieve both high performance and low power consumption
      and relies on a powerful fully coherent core complex based on
      a quad Cortex-A53 cluster with video and graphics accelerators
      
      this patch add the basic support for i.MX8MM.

      imx: make sure GIC redistributor is awake before initialization · e655fefc
      Anson Huang authored
      
      
      GICR_WAKER.ProcessorSleep can only be set to zero when:
      — GICR_WAKER.Sleep bit[0] == 0.
      — GICR_WAKER.Quiescent bit[31] == 0.
      
      On some platforms, when system reboot with GIC in sleep
      mode but with power ON, such as on NXP's i.MX8QM, Linux
      kernel enters suspend but could be requested to reboot,
      and GIC is in sleep mode and it is inside a power domain
      which is ON in this scenario, when CPU reset, the GIC
      driver trys to set CORE's redistributor interface to awake,
      with GICR_WAKER.Sleep bit[0] and GICR_WAKER.Quiescent bit[31]
      both set, the ProcessorSleep bit[1] will never be clear
      and cause system hang.
      
      This patch makes sure GICR_WAKER.Sleep bit[0] and
      GICR_WAKER.Quiescent bit[31] are both zeor before clearing
      ProcessorSleep bit[1].

      imx: power optimization for i.mx8qx · e6cf7a46
      Anson Huang authored
      
      
      Current implementation of i.MX8QX power management related
      features does NOT optimize power number, all system resources
      like CCI, DDR, and A cluster etc. are kept in STBY mode (powered
      ON) when system suspend or CPU hotplug.
      
      To lower the power number, OFF mode should be adopted for those
      system resources whenever they can be OFF, A cluster will be OFF
      if the CPUs in the cluster are all off line, DDR/MU/DB can be OFF
      if system suspend, IRQ steer can be OFF if the wakeup source is
      belonged to system controller partition, so wakeup source runtime
      check is used to determine if IRQ steer can be OFF before system
      suspend.
      
      If resources are powered off for suspend, they should be restored
      properly after system resume.

      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.

      drivers/console: Link console framework code by default · 985ee0b7
      Julius Werner authored
      
      
      This patch makes the build system link the console framework code by
      default, like it already does with other common libraries (e.g. cache
      helpers). This should not make a difference in practice since TF is
      linked with --gc-sections, so the linker will garbage collect all
      functions and data that are not referenced by any other code. Thus, if a
      platform doesn't want to include console code for size reasons and
      doesn't make any references to console functions, the code will not be
      included in the final binary.
      
      To avoid compatibility issues with older platform ports, only make this
      change for the MULTI_CONSOLE_API.

      Standardise header guards across codebase · c3cf06f1
      Antonio Nino Diaz authored
      
      
      All identifiers, regardless of use, that start with two underscores are
      reserved. This means they can't be used in header guards.
      
      The style that this project is now to use the full name of the file in
      capital letters followed by 'H'. For example, for a file called
      "uart_example.h", the header guard is UART_EXAMPLE_H.
      
      The exceptions are files that are imported from other projects:
      
      - CryptoCell driver
      - dt-bindings folders
      - zlib headers

      Add plat_crash_console_flush to platforms without it · 9c675b37
      Antonio Nino Diaz authored
      
      
      Even though at this point plat_crash_console_flush is optional, it will
      stop being optional in a following patch.
      
      The console driver of warp7 doesn't support flush, so the implementation
      is a placeholder.
      
      TI had ``plat_crash_console_init`` and ``plat_crash_console_putc``, but
      they weren't global so they weren't actually used. Also, they were
      calling the wrong functions.
      
      imx8_helpers.S only has placeholders for all of the functions.

      Multi-console: Deprecate the `finish_console_register` macro · cc5859ca
      Soby Mathew authored
      
      
      The `finish_console_register` macro is used by the multi console
      framework to register the `console_t` driver callbacks. It relied
      on weak references to the `ldr` instruction to populate 0 to the
      callback in case the driver has not defined the appropriate
      function. Use of `ldr` instruction to load absolute address to a
      reference makes the binary position dependant. These instructions
      should be replaced with adrp/adr instruction for position independant
      executable(PIE). But adrp/adr instructions don't work well with weak
      references as described in GNU ld bugzilla issue 22589.
      
      This patch defines a new version of `finish_console_register` macro
      which can spcify which driver callbacks are valid and deprecates the
      old one. If any of the argument is not specified, then the macro
      populates 0 for that callback. Hence the functionality of the previous
      deprecated macro is preserved. The USE_FINISH_CONSOLE_REG_2 define
      is used to select the new variant of the macro and will be removed
      once the deprecated variant is removed.
      
      All the upstream console drivers have been migrated to use the new
      macro in this patch.
      
      NOTE: Platforms be aware that the new variant of the
      `finish_console_register` should be used and the old variant is
      deprecated.
