      plat/arm: Fix header dependencies · 234bc7f8
      Antonio Nino Diaz authored
      
      
      From now on, platform_def.h must include any header with definitions that
      are platform-specific (like arm_def.h) and the included headers mustn't
      include back platform_def.h, and shouldn't be used by other files. Only
      platform_def.h should be included in other files. This will ensure that all
      needed definitions are present, rather than needing to include all the
      headers in all the definitions' headers just in case.
      
      This also prevents problems like cyclic dependencies.

      juno:Fix CSS_USE_SCMI_SDS_DRIVER=0 configuration · 3af72d57
      Joel Hutton authored
      A previous commit 89f2e589
      
       ("plat/arm: remove weak implemention of
      'plat_arm_psci_override_pm_ops' function") introduced a problem with the
      CSS_USE_SCMI_SDS_DRIVER configuration. In juno_pm.c the
      css_scmi_override_pm_ops function was used regardless of whether the
      flag was set. This patch ifdefs the function to restore the original
      behaviour.

      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/arm: Always define TSP memory region · 07146afb
      Antonio Nino Diaz authored
      
      
      Even though this is not used unless SPD=tspd, only defining it when
      SPD_tspd is defined doesn't have any advantage and it makes it harder to
      read the code.

      plat/arm/sgi: Use NT_FW_CONFIG instead of HW_CONFIG · 77ab969a
      Chandni Cherukuri authored
      
      
      With the two new APIs 'plat_arm_sgi_get_platform_id' and
      'plat_arm_sgi_get_config_id' that are available now, BL31 need not
      depend on hw_config device tree to identify the platform. In addition
      to this, the existing hardware description in hw_config can be limited
      to use by BL33 and not by the operating system.
      
      So the hardware description from hw_config dts can be moved into
      nt_fw_config dts and the use of hw_config dts can be removed.

      plat/arm/sgi: Use platform specific functions to get platform ids · 699223a2
      Chandni Cherukuri authored
      
      
      Add two new functions 'plat_arm_sgi_get_platform_id' and
      'plat_arm_sgi_get_config_id' which will be implemented by all the
      SGI platforms. These functions can be used to determine the part
      number and configuration id of the SGI platforms.
      
      In BL2, these functions are used to populate the 'system-id' node.
      In BL31, these functions are used to populate the 'sgi_plat_info_t'
      structure with the part number and configuration id of the platform.

      Synchronise arch.h and arch_helpers.h with TF-A-Tests · 932b3ae2
      Antonio Nino Diaz authored
      
      
      The headers forked at some point in the past and have diverged a lot. In
      order to make it easier to share code between TF-A-Tests and TF-A, this
      patch synchronises most of the definitions in the mentioned headers.
      
      This is not a complete sync, it has to be followed by more cleanup.
      
      This patch also removes the read helpers for the AArch32 instructions
      ats1cpr and ats1hr (they are write-only).

      This patch adds support to build a combined BL1
      and ROMLIB binary file with the right page
      alignment in Juno. When USE_ROMLIB=1 is set for
      Juno, it generates the combined file
      bl1_romlib.bin which needs to be used instead of
      bl1.bin

      SPM: Register Secure Partition priority level with ehf module · 5681b292
      Sughosh Ganu authored
      
      
      Register a priority level, PLAT_SP_PRI, for secure partition with EL3
      exception handling framework(ehf) module.
      
      The secure partition manager(SPM) would raise the core's priority to
      PLAT_SP_PRI before entering the secure partition, to protect the core
      from getting interrupted while in secure partition.

      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
