      plat: marvell: armada: a3k: Add new compile option A3720_DB_PM_WAKEUP_SRC · f2800a47
      Pali Rohár authored
      
      
      This new compile option is only for Armada 3720 Development Board. When
      it is set to 1 then TF-A will setup PM wake up src configuration.
      
      By default this new option is disabled as it is board specific and no
      other A37xx board has PM wake up src configuration.
      
      Currently neither upstream U-Boot nor upstream Linux kernel has wakeup
      support for A37xx platforms, so having it disabled does not cause any
      issue.
      
      Prior this commit PM wake up src configuration specific for Armada 3720
      Development Board was enabled for every A37xx board. After this change it
      is enabled only when compiling with build flag A3720_DB_PM_WAKEUP_SRC=1

      plat: marvell: armada: a3k: support doing system reset via CM3 secure coprocessor · d9243f26
      Marek Behún authored
      
      
      Introduce a new build option CM3_SYSTEM_RESET for A3700 platform, which,
      when enabled, adds code to the PSCI reset handler to try to do system
      reset by the WTMI firmware running on the Cortex-M3 secure coprocessor.
      (This function is exposed via the mailbox interface.)
      
      The reason is that the Turris MOX board has a HW bug which causes reset
      to hang unpredictably. This issue can be solved by putting the board in
      a specific state before reset.

      plat: marvell: armada: modify PLAT_FAMILY name for 37xx SoCs · b5c850d4
      Marcin Wojtas authored
      
      
      The Marvell Armada 37xx SoCs-based platforms contain a bit
      awkward directory structure because the currently only one
      supported PLAT and PLAT_FAMILY are the same. Modify the latter
      to 'a3k' in order to improve it and keep plat/marvell/armada
      tree more consistent:
      
      plat/marvell/
      ├── armada
      │   ├── a3k
      │   │   ├── a3700
      
      [...]
      
      │   ├── a8k
      │   │   ├── a70x0

      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.

      plat: marvell: a3700: do not power off cpu due to errata ref #13 · 9cb6751d
      Grzegorz Jaszczyk authored
      
      
      Do not power off the CPU1 since there is no way to wake it up
      (wake-up is causing CPU0 reset as well duo to HW bug). Quote from errata
      Ref #13 [In power saving mode, both cores must be powered off]:
      "When Core 0 is on and Core 1 is in power-off state, a Core 1
      wake-up resets Core 0 as well and puts Core 0 back to ROM".
      
      To overcome described HW bug instead of powering the CPU off, let it
      reach WFI instruction, which is invoked by generic psci_do_cpu_off
      function after platform handler finishes. This will put the core in low
      power state and give a chance to wake it up.
      
      Before this change, after running secondary kernel via kexec, only one
      core was up, now both cores are up.
