      plat/arm: Fix BL31_BASE when RESET_TO_BL31=1 · fd5763ea
      Qixiang Xu authored
      
      
      The value of BL31_BASE currently depends on the size of BL31. This
      causes problems in the RESET_TO_BL31 case because the value of
      BL31_BASE is used in the model launch parameters, which often changes.
      
      Therefore, this patch fixes BL31_BASE to the middle of Trusted SRAM,
      to avoid further model parameter changes in future.

      Implement log framework · 7f56e9a3
      Soby Mathew authored
      
      
      This patch gives users control over logging messages printed from the C
      code using the LOG macros defined in debug.h Users now have the ability
      to reduce the log_level at run time using the tf_log_set_max_level()
      function. The default prefix string can be defined by platform by
      overriding the `plat_log_get_prefix()` platform API which is also
      introduced in this patch.
      
      The new log framework results in saving of some RO data. For example,
      when BL1 is built for FVP with LOG_LEVEL=LOG_LEVEL_VERBOSE, resulted
      in saving 384 bytes of RO data and increase of 8 bytes of RW data. The
      framework also adds about 108 bytes of code to the release build of FVP.
      
      Fixes ARM-software/tf-issues#462

      CSS: Changes for SDS framework · 18e279eb
      Soby Mathew authored
      
      
      This patch does the required changes to enable CSS platforms
      to build and use the SDS framework. Since SDS is always coupled with
      SCMI protocol, the preexisting SCMI build flag is now renamed to
      `CSS_USE_SCMI_SDS_DRIVER` which will enable both SCMI and SDS on
      CSS platforms. Also some of the workarounds applied for SCMI are
      now removed with SDS in place.

      cert_tool: Support for legacy RSA PKCS#1 v1.5 · a8eb286a
      Soby Mathew authored
      
      
      This patch enables choice of RSA version at run time to be used for
      generating signatures by the cert_tool. The RSA PSS as defined in
      PKCS#1 v2.1 becomes the default version and this patch enables to specify
      the RSA PKCS#1 v1.5 algorithm to `cert_create` through the command line
      -a option. Also, the build option `KEY_ALG` can be used to pass this
      option from the build system. Please note that RSA PSS is mandated
      by Trusted Board Boot requirements (TBBR) and legacy RSA support is
      being added for compatibility reasons.

      Export KEY_ALG as a user build option · 2091755c
      Soby Mathew authored
      
      
      The `KEY_ALG` variable is used to select the algorithm for key
      generation by `cert_create` tool for signing the certificates. This
      variable was previously undocumented and did not have a global default
      value. This patch corrects this and also adds changes to derive the
      value of `TF_MBEDTLS_KEY_ALG` based on `KEY_ALG` if it not set by the
      platform. The corresponding assignment of these variables are also now
      removed from the `arm_common.mk` makefile.

      Add usage note for FVP model versions 11.0 and 8.5 · 279fedc1
      David Cunado authored
      
      
      The internal synchronisation timings of the FVP model version
      11.0 build 11.0.34 and version 8.5 build 0.8.5202 has been
      changed compared to older version of the models.
      
      This change may have an impact on how the model behaves depending
      on the workload being run on the model. For example test failures
      have been seen where the primary core has powered on a secondary
      core but was then starved of host CPU time and so was not able to
      update power status, resulting a test failure due to an incorrect
      status. This, or similar behaviour, is not to be expected from
      real hardware platforms.
      
      This patch adds a usage note on how to launch these models so
      that internal synchronisation timing matches that of the older
      version of the models, specifically adding the -Q 100 option.

      Introduce bolean build directive SP_MIN_WITH_SECURE_FIQ to enable

      Configure SCR[FIQ] and SCR[FW] from generic code for both cold and
      warm boots to handle FIQ in secure state from monitor.
      
      Since SP_MIN architecture, FIQ are always trapped when system executes
      in non secure state. Hence discard relay of the secure/non-secure
      state in the FIQ handler.

      CCI: Adapt for specific product at run time · e33fd445
      Jeenu Viswambharan authored
      
      
      The current build system and driver requires the CCI product to be

      time from its ID registers, obviating the need for specifying them
      ahead.
      
      This patch adds changes to identify and validate CCI at run time. Some
      global variables are renamed to be in line with the rest of the code
      base.
      
      The build option ARM_CCI_PRODUCT_ID is now removed, and user guide is

      FVP: Add support for multi-threaded CPUs · 11ad8f20
      Jeenu Viswambharan authored
      
      
      ARM CPUs with multi-threading implementation has more than one
      Processing Element in a single physical CPU. Such an implementation will
      reflect the following changes in the MPIDR register:
      
        - The MT bit set;
      
        - Affinity levels pertaining to cluster and CPUs occupy one level
          higher than in a single-threaded implementation, and the lowest
          affinity level pertains to hardware threads. MPIDR affinity level
          fields essentially appear shifted to left than otherwise.
      
      The FVP port henceforth assumes that both properties above to be
      concomitant on a given FVP platform.
      
      To accommodate for varied MPIDR formats at run time, this patch
      re-implements the FVP platform-specific functions that translates MPIDR
      values to a linear indices, along with required validation. The same
      treatment is applied for GICv3 MPIDR hashing function as well.
      
      An FVP-specific build option FVP_MAX_PE_PER_CPU is introduced which
      specifies the maximum number of threads implemented per CPU. For
      backwards compatibility, its value defaults to 1.

      Emphasize that TF only supports 4 KB granule size · de3d704d
      Sandrine Bailleux authored
      
      
      At the moment, various parts of the Trusted Firmware code assume
      that the granule size used is 4 KB. For example, the linker scripts
      enforce 4 KB alignment restrictions on some sections.
      
      However, the ARMv8-A architecture allows 16 KB and 64 KB granule
      sizes as well. Some other parts of the TF code, particularly the
      architectural code and definitions, have been implemented with
      this in mind and cater for all 3 cases.
      
      This discrepancy creates some confusion as to what is effectively
      supported in TF. This patch adds some code comments and clarification
      in the documentation to make this limitation clearer.
